Why Is There Confusion over the Plural of Zoo?There is confusion because the rule for forming plurals with nouns ending in o isn't straightforward. Most nouns will just add an s. For example:
- Kangaroo becomes kangaroos.
- Piano becomes pianos.
- Echo becomes echoes.
- Torpedo becomes torpedoes.
- Volcano becomes volcanoes or volcanos.
- Halo becomes haloes or halos.
Don't Use an Apostrophe to Form a PluralAdding 's is never an option when forming the plural of a noun. Despite this simple rule, inexperienced writers often feel compelled to add an apostrophe, especially when the noun ends with a vowel (e.g., piano, tomato, emu). For example:
- Young kangaroo's are called joeys.
- Young kangaroos are called joeys.
