Grammar notes

🚌 Watch the Ending! (Plural Spelling Rules)

Some plural nouns need a little more than just -s. Words like bus and box often take -es. Words ending in consonant + y often change to -ies. So the end of the word tells you how the plural wants to dress.

• Example: bus → buses
• Example: baby → babies

Quick Rule

• -s / -x / -ch / -sh → usually -es
• consonant + y → -ies

Look at the last letters. They are giving you the spelling clue.
