Hyphens

• Punctuation marks help the reader understand what the writer is trying to say

• A hyphen looks like this - and is slightly shorter than a dash

• Hyphens are used to join together two or three words to form a compound word such as check-in

• Compound numbers between 21 and 99 use hyphens such as twenty-one

• Hyphens join prefixes to words such as self-confident

• Hyphens can also be used to split a word when it is too long to fit at the end of a line
