Finding the right word can be one of the most frustrating challenges for a person with aphasia. Someone may know exactly what they want to say but be unable to retrieve the word, even though it feels as though it is “on the tip of their tongue”.
Semantic therapy is one approach speech pathologists use to support word retrieval. It focuses on the meaning of words and the connections between related words, objects, actions and ideas.
In this article, we explain how semantic therapy works and provide some simple exercises that may be practised at home.
What is aphasia?
Aphasia is an acquired language disorder caused by damage to the areas of the brain responsible for language. It commonly occurs following a stroke but may also result from traumatic brain injury, brain tumours, infections or progressive neurological conditions.
Aphasia can affect a person’s ability to:
find and say words
understand spoken language
form sentences
read
write
participate confidently in conversation.
Aphasia does not mean that someone has lost their intelligence. The person may still have a clear idea of what they want to communicate but have difficulty accessing or expressing the words.
The type and severity of aphasia differ considerably between individuals, which is why assessment and therapy should be personalised.
What is semantic therapy for aphasia?
The word semantic refers to meaning.
Semantic therapy helps a person explore the meaning of a word rather than repeatedly trying to say the word on its own. The person may think about the word’s category, function, appearance, location, properties or related ideas.
For example, when trying to retrieve the word apple, the person might discuss:
Category: It is a fruit
Function: You eat it
Appearance: It may be red, green or yellow
Shape: It is usually round
Location: You might find it in a fruit bowl, lunchbox or supermarket
Associated words: Orchard, juice, pie, seeds and healthy snack
Activating these related meanings may make it easier for the person to retrieve the target word.
One widely used semantic treatment is Semantic Feature Analysis, often shortened to SFA. Research reviews have found that SFA can improve the naming of words practised during therapy for many people with aphasia. However, improvement does not always automatically carry over to unfamiliar words or everyday conversation. This is why therapy should include meaningful vocabulary and opportunities to use the words in real situations.
Watch semantic therapy in action
The following short video from Enable Speech Pathology demonstrates examples of semantic therapy techniques that can be used to support word finding.
The video shows how a person can be encouraged to think about related meanings and information rather than becoming stuck repeatedly attempting the missing word.
Semantic therapy should feel like guided exploration—not a test. The purpose is to activate useful information and support communication, even when the exact word does not immediately appear.
What words should you practise at home?
Begin with words that are:
familiar
personally meaningful
useful in daily life
connected to the person’s interests and routines
challenging enough to require practice without causing excessive frustration.
Examples might include:
names of family members
favourite foods
household items
gardening equipment
clothing
medications
places the person regularly visits
hobbies
television programs
sporting terms
words needed when attending appointments.
A person who enjoys gardening may benefit more from practising words such as secateurs, watering can, fertiliser and seedlings than from practising unrelated pictures selected at random.
Exercise 1: Semantic Feature Analysis
Choose a photograph or real object and ask the person to name it.
When the word is difficult to retrieve, work through some meaning-based questions.
Questions to ask
1. What group or category does it belong to?
2. What do you do with it?
3. Where would you normally find it?
4. What does it look like?
5. What does it feel, smell or taste like?
6. What parts does it have?
7. What does it remind you of?
8. What other words are associated with it?
After discussing the features, ask the person to try naming the item again.
Example: “Kettle”
It is a kitchen appliance.
It heats water.
You find it in the kitchen.
It may be made of metal or plastic.
It has a handle, lid and spout.
It is associated with tea, coffee and boiling water.
The person may retrieve the word while discussing these features. When that happens, acknowledge the success and continue naturally rather than demanding repeated production.
Exercise 2: Describe the object without naming it
Place several everyday objects on a table. Take turns choosing an object and describing it without saying its name.
For example:
“You find it in the kitchen. It has a handle. You drink tea or coffee from it.”
The other person guesses cup.
This activity practises word meanings while also teaching a useful communication strategy. During a real conversation, the person may be able to describe a missing word even when they cannot retrieve its name.
Useful household items include:
cup
spoon
key
phone
book
toothbrush
remote control
wallet
glasses
saucepan
Exercise 3: Category sorting
Collect photographs, written words or household objects and sort them into groups.
Possible categories include:
food and drinks
clothing
tools
bathroom items
kitchen items
animals
transport
furniture
places
Make the activity more challenging by using narrower categories, such as:
fruit versus vegetables
hot drinks versus cold drinks
indoor clothing versus outdoor clothing
garden tools versus household tools
things kept in the fridge versus things kept in the cupboard
After sorting, ask the person to name each item or explain why it belongs in that group.
Exercise 4: Name items within a category
Choose a category and ask the person to name several examples.
For example:
“Can you name some animals?”
Possible answers might include dog, cat, horse and kangaroo.
More functional examples include:
things you buy at the supermarket
things you take to a medical appointment
items used when making tea
things found in the garden
people in your family
places you visit during the week
things needed before leaving the house
Avoid placing pressure on the person to produce a large number of words quickly. Allow time, provide encouragement and offer clues when required.
Exercise 5: Find the item that does not belong
Present four words or pictures, with three belonging to the same category.
For example:
Apple – banana – orange – chair
The person identifies chair as the item that does not belong and explains why.
Other examples include:
fork – spoon – plate – shoe
dog – horse – cat – bus
shirt – trousers – jumper – toaster
Adelaide – Sydney – Melbourne – carrot
doctor – nurse – physiotherapist – refrigerator
Explaining the reason is an important part of the activity because it encourages deeper processing of word meaning.
Exercise 6: Word associations
Say a word and ask the person to produce something associated with it.
Examples include:
coffee → cup;
beach → sand;
rain → umbrella;
doctor → hospital;
birthday → cake;
garden → flowers; and
key → door.
There may be more than one correct answer.
You can also reverse the activity by giving several clues:
“Hot, drink, morning, mug.”
The person identifies the related word coffee
Exercise 7: Finish the sentence
Provide a meaningful sentence and leave out the final word.
For example:
I clean my teeth with a ______.
I unlock the door with a ______.
I drink tea from a ______.
I put my groceries in the ______.
I wear glasses so I can ______.
When it rains, I use an ______.
Use sentences that are familiar and relevant to the person’s life.
The person may find it easier to retrieve a word when it appears within a meaningful sentence than when naming a picture in isolation.
Exercise 8: Practise action words
Word-finding difficulties can affect verbs as well as object names.
Choose a photograph, video or real activity and discuss the action taking place.
For example, for the word cutting, ask:
Who is doing it?
What are they cutting?
What are they using?
Where are they?
Why are they cutting it?
What might happen next?
Other action words to practise include:
cooking
washing
driving
reading
planting
opening
carrying
shopping
pouring
writing
Action words can then be placed into short sentences, such as:
“The man is cutting the bread.”
Exercise 9: Use photographs from the person’s own life
Personal photographs can provide meaningful opportunities to practise names, places, actions and events.
Choose one photograph and discuss:
who is in it
where they are
what they are doing
what objects are visible
how the people may be feeling
what happened before the photograph
what may have happened afterwards
Do not correct every error. The goal is successful and enjoyable communication, not perfect performance.
Exercise 10: Use semantic strategies during everyday activities
Semantic practice does not always need to take place at a table.
You can include it naturally while:
putting groceries away;
preparing a meal;
folding clothes;
gardening;
looking through photographs;
watching television;
walking around the neighbourhood; or
planning the week.
For example, while preparing lunch, you might discuss the category, purpose, appearance and location of the ingredients and utensils being used.
This allows the person to practise words in the same context in which they may later need them.
How can family members provide helpful cues?
When someone cannot find a word, avoid immediately supplying it unless they appear distressed or ask for help.
Try a gradual sequence of cues:
1. Allow time. Pause and give the person an opportunity to retrieve the word.
2. Ask for a description. “What do you do with it?”
3. Provide a semantic clue. “It is something you drink from.”
4. Offer a sentence starter. “I drink my coffee from a…”
5. Provide the first sound. “It starts with /k/.”
6. Offer two choices. “Is it a cup or a plate?”
7. Say the word when further searching is becoming frustrating.
A cue should help the person—not make them feel tested.
How long should home practice last?
Short, regular practice is usually more manageable than a long and tiring session.
A starting point may be:
10 to 15 minutes;
three or four times per week;
approximately five useful words at a time; and
regular revision of previously practised words.
Some people will manage more and others will require shorter sessions.
Stop or change the activity when the person becomes tired, upset or increasingly frustrated. Fatigue can significantly affect communication after stroke or brain injury.
Keep communication successful!
The purpose of semantic therapy is not simply to produce correct answers during an exercise. The broader goal is to help the person communicate more effectively and confidently.
Accept other ways of communicating, including:
gestures
pointing
drawing
writing
showing an object
using photographs
describing the word
using a communication device
Successfully conveying the message is more important than retrieving one particular word.
When should you see a speech pathologist?
Home activities are most useful when they complement an individualised speech pathology program.
A speech pathologist can assess:
the nature and severity of the aphasia
whether the primary difficulty involves word meaning, speech sounds or both
comprehension
reading and writing
sentence formation
functional communication
the most appropriate cues and therapy approaches
Semantic therapy may be highly useful for one person but less suitable as the main treatment for another. Therapy may also need to incorporate phonological cueing, script training, sentence-level treatment, reading and writing therapy, supported conversation strategies or augmentative and alternative communication.
At Enable Speech Pathology, therapy is personalised around the person’s communication needs, daily routines, interests and goals.
