Let's solve the task of converting singular nouns to their plural forms. We'll go through each noun and apply the correct pluralization rules.

🔹 General Rules for Plural Nouns:

1. Most nouns: Add -s
→ *pen → pens*
2. Nouns ending in -s, -sh, -ch, -x, -z: Add -es
→ *brush → brushes*
3. Nouns ending in -y (preceded by a consonant): Change -y → -ies
→ *baby → babies*
4. Nouns ending in -f or -fe: Often change to -ves
→ *knife → knives*, *leaf → leaves*
*(But some just add -s: "roof" → "roofs")*
5. Irregular plurals: These don’t follow standard rules
→ *child → children*, *mouse → mice*, *man → men*, etc.
6. Words like "octopus", "butterfly", "photo": Use -s or -es, but some have irregular or borrowed forms
→ *butterfly → butterflies*, *photo → photos*, *octopus → octopuses* or *octopi* (less common)

✔ Explanation of Key Entries:

- pen, pencil, book, chair, table, window, bed, video, hand, eye, photo, video – All regular nouns; add -s
- bus → ends in -s, so we add -es → buses
- box → ends in -x, so add -es → boxes
- shoe → regular, just add -s → shoes
- butterfly → ends in -y after a consonant (l) → change -y → -ies → butterflies
- photo → ends in -o, but it's a common word that takes -s → photos
- brush → ends in -sh, so add -es → brushes
- peach → ends in -ch, so add -es → peaches
- baby → ends in -y after consonant (b) → babies
- candy → ends in -y after consonant (d) → candies
- octopus → This is tricky. The most common plural form is octopuses (add -es). Alternatives like octopi (Latin-based) are less common and often considered incorrect in modern English.
