- -ful means full of.
- -less means without.
- -ly often turns an adjective into an adverb.
Words to know
a word part added to the end
full of
without
in a certain way
1. Discover: The careful cook
Ama is a careful cook. She is never careless. Her food is tasty and she is always helpful. She stirs slowly and quietly. Kofi is a good teacher. “I am hopeful,” says Ayo, “that I can cook like her.”
Think: What do the endings -ful and -less do?
2. Understand: Suffixes
Idea 1: What is a suffix?
A suffix is a word part added to the end of a word: care + ful = careful.
Idea 2: Common suffixes
-ful means full of (careful). -less means without (careless). -ly means in a way (slowly). -er means a person who (teacher).
Idea 3: Spelling
Usually just add the suffix. If the word ends in y, change y to i before -ful: beauty + ful = beautiful.
3. Worked examples
Example 1 (I show you): Add
care + ful = ?
- Full of care.
Answer: careful
Example 2 (We do it together): Without
hope + less = ?
- Without hope.
Answer: hopeless
Example 3 (You try): Way
slow + ly = ?
Show the steps and answer
- In a slow way.
Answer: slowly
Did you know?
Suffixes can change a word from one job to another, such as quick to quickly.

Courseversity badge thresholds (overall quiz score): Gold = 90–100%; Silver = 80–89.9%; Bronze = 70–79.9%. A badge is never a full record of progress.
If a learner struggles
- Find the misconception: Adding to the start. Suffixes go at the end.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Use suffix cards.
- Guided practice: work through one example together and let the learner try the next one.
- Reassess: use the quiz again or the worksheet.
- Move on when the learner shows Silver-level evidence independently.
For parents and guardians
In this lesson your child learns common suffixes. You do not need to be an expert to help.
- Hunt for suffix words.
- Play with meanings.
- Praise noticing.
- Ask “how do you know?” after each answer, and listen.
- Praise effort, not only right answers. Mistakes are how we learn.
- Ten to fifteen minutes a day is better than one long session.
