Suffixes worksheet for children to practice adding suffixes to words.

Explanation:
We are given three suffixes to choose from: able, ful, and ly.
We need to add one of these to each base word to make a real, correct English word.

Let’s go one by one:

1. admir__
Think: *admire* is the verb. If we want to say “full of admiration” or “worthy of admiration”, we use admirable.
✔ *admirable* = admire + able
(Note: *admirful* and *admirly* are not real words.)

2. agree__
We often say *agreeable* — meaning pleasant or willing to agree.
✔ *agreeable* = agree + able
(*agreeful* and *agreely* are not standard English words.)

3. arm__
Think of *armful* — as in “an armful of books” (meaning as much as you can hold in your arms).
✔ *armful* = arm + ful
(*armable* is rare and not common; *armly* is not a word.)

4. care__
Two possibilities: *careful* and *carefully*. But note: we only get to use one suffix per word, and the suffixes listed are *able*, *ful*, *ly* — all single options.
- *careful* = care + ful → valid
- *carefully* = careful + ly, but that would require adding *ly* to *careful*, not directly to *care*. Since the base is *care*, and we’re adding just one suffix, careful is the correct choice here.
✔ *careful*

5. color__
Common word: *colorful* = color + ful
(In US English it's *color*, in UK *colour*, but the base here is *color*, so *colorful* is correct.)
✔ *colorful*
(*colorable* exists but is rare and technical; *colorly* is not a word.)

So the correct suffixes are:
1. able → admirable
2. able → agreeable
3. ful → armful
4. ful → careful
5. ful → colorful

Final Answer:
1. able
2. able
3. ful
4. ful
5. ful
