Singular and Plural Nouns worksheet for practicing noun conversion.

Let’s go through each word one by one. The rule is:
- If it’s a singular noun, make it plural.
- If it’s a plural noun, make it singular.

But wait — looking at the list, all the words given are actually singular nouns! So we just need to turn each one into its plural form.

Here’s how we do it:

Most nouns just add “s” → like “dragon” → “dragons”

Some end in “y” → if the letter before “y” is a consonant, change “y” to “ies” → like “daisy” → “daisies”, “spy” → “spies”

Some end in “ch”, “sh”, “x”, “s”, or “z” → add “es” → like “beach” → “beaches”, “fox” → “foxes”

Some end in “fe” or “f” → sometimes change to “ves” → but not always! For example, “knife” → “knives”, but “roof” → “roofs”. In this list, we have “apostrophe” → that ends in “e”, so just add “s” → “apostrophes”

Also, some words like “company” → change “y” to “ies” → “companies”

Let’s go step by step for each:

(1) power → powers
(2) dragon → dragons
(3) file → files
(4) charm → charms
(5) whiteboard → whiteboards
(6) wish → wishes (ends in “sh”)
(7) empty → empties (ends in “y” after consonant)
(8) fax → faxes (ends in “x”)
(9) daisy → daisies (ends in “y” after consonant)
(10) disc → discs
(11) phone → phones
(12) spy → spies (ends in “y” after consonant)
(13) key → keys (ends in “y” but after vowel? Wait — “key” ends in “ey”, which is vowel + y → so just add “s” → keys)
Actually, let me double-check: “key” → yes, it’s “keys” because “e” is a vowel before “y”. Same with “boy” → “boys”. But “city” → “cities” because “t” is consonant before “y”.

So correction:
(13) key → keys (vowel before y → just add s)

(14) enemy → enemies (consonant before y → ies)
(15) reality → realities (consonant before y → ies)
(16) critic → critics
(17) backpack → backpacks
(18) fox → foxes (ends in “x”)
(19) apostrophe → apostrophes

Now right column:

(20) beach → beaches (ends in “ch”)
(21) staple → staples
(22) trench → trenches (ends in “ch”)
(23) penny → pennies (consonant before y → ies)
(24) company → companies (consonant before y → ies)
(25) dinner → dinners
(26) gallery → galleries (consonant before y → ies)
(27) girl → girls
(28) sky → skies (consonant before y → ies)
(29) gas → gases (ends in “s” → add “es”)
Wait — “gas” → plural is “gases” (pronounced “gaz-ez”) — yes, correct.
(30) library → libraries (consonant before y → ies)
(31) atrocity → atrocities (consonant before y → ies)
(32) keyboard → keyboards
(33) party → parties (consonant before y → ies)
(34) club → clubs
(35) lunch → lunches (ends in “ch”)
(36) match → matches (ends in “ch”)
(37) bush → bushes (ends in “sh”)
(38) branch → branches (ends in “ch”)

Let me verify tricky ones again:

- “empty” → “empties” ✔
- “fax” → “faxes” ✔
- “daisy” → “daisies” ✔
- “spy” → “spies” ✔
- “key” → “keys” ✔ (because “e” is vowel)
- “enemy” → “enemies” ✔
- “reality” → “realities” ✔
- “fox” → “foxes” ✔
- “apostrophe” → “apostrophes” ✔
- “beach” → “beaches” ✔
- “penny” → “pennies” ✔
- “company” → “companies” ✔
- “gallery” → “galleries” ✔
- “sky” → “skies” ✔
- “gas” → “gases” ✔
- “library” → “libraries” ✔
- “atrocity” → “atrocities” ✔
- “party” → “parties” ✔
- “lunch” → “lunches” ✔
- “match” → “matches” ✔
- “bush” → “bushes” ✔
- “branch” → “branches” ✔

All look good!
