Hyphens are the short lines (-) that we put between the words in expressions like ex-husband or ticket-office.

Hyphens are most often used in the following cases:
a compound noun where the second part ends in -er
lorry-driver

compound nouns where the first part ends in -ing
waiting-room

compound nouns made with prepositions and adverb particles
sister-in-law

compound adjectives

red-hot      nice-looking     the Tehran-Washington flight

compound verbs beginning with a noun

baby-sit

prefixes 
the prefixes anti-, co-, ex-, mid-, non-, pre-, post-,.. are often separated from what follows by hyphens.
anti-war    pre-meeting   

numbers 21-99; fractions
thirty-six    

I hope it makes sense!!
