A compound noun is a noun that
is made up of two or more words. Most compound nouns in English are formed by
nouns modified by other nouns or adjectives.
a.The words tooth and paste
are each nouns in their own right, but if you join them together they form a
new word - toothpaste.
b.The word black is an adjective
and board is a noun, but if you join them together they
form a new word - blackboard.
In both these example the first word modifies or describes
the second word, telling us what kind of object or person it is, or what its
purpose is. And the second part identifies the object or person in question.

1. Sometimes the two words are joined together.

1.Normally the last word is made plural:
Boy-friends break-ins travel

drivers women drivers

Hangers-on lookers-on runners-up
And with compound
composed of noun+preposition+noun:
Ladies-in-waiting sister-in-law wards of court
