plural form of city is cities.

In the English language, nouns can be categorized into singular and plural forms. A singular noun refers to one individual or object, whereas a plural noun refers to multiple individuals or objects. To form the plural of certain nouns, specific rules are applied. Let's explore the rule for forming the plural of "city."

When a noun ends with a consonant followed by the letter -y, the -y is replaced with -ies to form its plural. For example:

• Plural of City becomes Cities
• Plural of Lady becomes Ladies

This is different from nouns ending with a vowel followed by -y, where simply adding an -s forms the plural. For example:

• Key becomes Keys
• Day becomes Days

Incorrect options like "citves," "cityes," and "citieos" do not follow these rules and are not valid plural forms. These terms are not recognized in dictionaries and lack linguistic meaning.

Therefore, based on the rules, the plural form of city is cities.
