Let’s go through each word one by one. We need to decide: when we add the ending (like -er, -es, or -s), do we change the “y” to an “i”? Then we write the new word with correct spelling.
Rule reminder (simple version):
If a word ends in “y” and the letter before it is a consonant → change y to i before adding endings like -es, -er, -ed.
If the letter before “y” is a vowel (a, e, i, o, u) → keep the “y”.
Now let’s solve each box:
---
funny + -er
“funny” ends in “y”, and before “y” is “n” (consonant) → YES, change y to i → funnier
✔ Y to I? Yes
Word:
funnier
---
baby + -es
“baby” ends in “y”, before “y” is “b” (consonant) → YES, change y to i → babies
✔ Y to I? Yes
Word:
babies
---
happy + -er
“happy” ends in “y”, before “y” is “p” (consonant) → YES, change y to i → happier
✔ Y to I? Yes
Word:
happier
---
play + -er
“play” ends in “y”, but before “y” is “a” (vowel!) → NO, don’t change y → player
✔ Y to I? No
Word:
player
---
lazy + -er
“lazy” ends in “y”, before “y” is “z” (consonant) → YES, change y to i → lazier
✔ Y to I? Yes
Word:
lazier
---
lady + -es
“lady” ends in “y”, before “y” is “d” (consonant) → YES, change y to i → ladies
✔ Y to I? Yes
Word:
ladies
---
enemy + -es
“enemy” ends in “y”, before “y” is “m” (consonant) → YES, change y to i → enemies
✔ Y to I? Yes
Word:
enemies
---
fly + -er
“fly” ends in “y”, before “y” is “l” (consonant) → YES, change y to i → flier (or flyer — both are accepted, but for this rule, we follow the pattern: fly → flier)
✔ Y to I? Yes
Word:
flier *(Note: “flyer” is also common, but since we’re practicing the rule, we use “flier”)*
Wait — actually, “fly” is a special case. In real life, people say “flyer” more often. But according to strict grammar rules for this worksheet, since “l” is a consonant, we should change y to i → flier. Let’s stick with the rule for now.
✔ Y to I? Yes
Word:
flier
---
key + -s
“key” ends in “y”, but before “y” is “e” (vowel!) → NO, don’t change y → keys
✔ Y to I? No
Word:
keys
---
story + -es
“story” ends in “y”, before “y” is “r” (consonant) → YES, change y to i → stories
✔ Y to I? Yes
Word:
stories
---
body + -es
“body” ends in “y”, before “y” is “d” (consonant) → YES, change y to i → bodies
✔ Y to I? Yes
Word:
bodies
---
try + -es
“try” ends in “y”, before “y” is “r” (consonant) → YES, change y to i → tries
✔ Y to I? Yes
Word:
tries
---
Final Answer:
