In this post, you’ll find out the correct punctuation rules, use cases, and sentence examples for “year and a half”.
Should “Year And A Half” Use Hyphens?

Here are some examples of “year and a half” used as a compound adjective.

- Year-and-a-half long assignment

In these examples, “year and a half” is used as a compound adjective to describe the noun (project, assignment, task, etc.). We learned in our post about in-person hyphenation that punctuation highly depends on the context of the writing!
When Should Hyphens Be Used?
A hyphen is a short horizontal line that fills the space between two words. Just like we learned in our post on grammar & punctuation, there are many different situations in which a hyphen could be used. Here a few of the different situations where a hyphen could be inserted.
- Compound words: Hyphens are used to join two (or more) words that are paired or modify a specific noun. (i.e. Well-being, self-esteem, high-level)
- Prefixes and Suffixes: Hyphens are used with certain prefixes and suffixes to provide clarification or clarity. (i.e. pre-employment, non-English, ex-boyfriend)
- Numbers and Fractions: Hyphens are used in compound numbers and fractions. (i.e. thirty-two, two-thirds, three-quarters)
- Adjective-Noun Combinations: Hyphens are used to connect compound adjectives before a noun. (i.e. well-known author, fast-paced game, blue-eyed baby)
- Suspended Hyphens: Hyphens are used to avoid repetition when multiple prefixes are used. (i.e. high- and low-income earners)
Just like we saw in our post about the expression “including but not limited to“, punctuation is very important to the meaning of a sentence!
