Words that end with S are words whose final letter is the alphabet S. These words can be nouns, verbs, adjectives, or proper nouns. This includes:

  • Plural nouns, such as books, chairs, and pencils

  • Singular nouns that naturally end in S, such as bus, gas, and lens

  • Verbs in the present tense (third person singular form), such as runs, plays, and jumps

  • Words where S is simply part of the root spelling, such as always, glass, and yes

 

Why Do Words End With S?

There are several reasons why English words end with S.

  • To show plural nouns: Adding S often indicates more than one person, place, animal, or object. Examples:

    • Apple → apples

    • river → rivers

    • student → students

  • To form third-person singular verbs: In the simple present tense, verbs often take S when used with he, she, or it. Examples:

    • write → writes

    • Jump → jumps

  • To show possession: An apostrophe and S can indicate ownership. Examples:

    • Teacher's notebook

    • child's project

Rules and Tips for Adding S at the End

When forming plurals or present tense verbs, keep these tips in mind:

  • Add S for most words: Book becomes books, walk becomes walks.

  • Add ES after certain endings: Words ending in ch, sh, ss, x, or z usually take ES instead of just S, for example box becomes boxes and church becomes churches.

  • Change Y to IES: If a word ends in a consonant followed by Y, change the Y to I and add ES, for example baby becomes babies.

  • Keep Y and add S: If the word ends in a vowel followed by Y, simply add S, for example toy becomes toys.

  • Watch for irregular plurals: Some words do not follow the standard S rule at all, such as child becoming children or mouse becoming mice.

 

Apostrophes With Words and Names Ending in S

Apostrophes can be tricky with words and names that already end in S. Here is a simple breakdown:

  • Singular noun ending in S: Add an apostrophe and another S, for example the bus's engine, or James's book. Some style guides accept just an apostrophe after the S for names, such as James' book, so both forms may be seen depending on the guide being followed.

  • Plural noun ending in S: Add only an apostrophe after the S, for example the students' classroom, meaning a classroom belonging to more than one student.

  • Plural noun not ending in S: Add an apostrophe and an S, for example the children's toys.
