Unit 11
1. COMPOUNDS
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.

For example:
ü  The words tooth and paste are each nouns in their own right, but if you join them together they form a new word - toothpaste.

ü  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.

Compound nouns can also be formed using the following combinations of words:-
Noun
+
Noun
toothpaste
Adjective

Noun
monthly ticket
Verb

Preposition

Verb

Preposition

Adjective

Verb

Verb

 The two parts may be written in a number of ways:-
1. Sometimes the two words are joined together.
    Example: tooth + paste = toothpaste | bed + room = bedroom

2. Sometimes they are joined using a hyphen.
     Example: check-in

3. Sometimes they appear as two separate words.
     Example: full moon

3. British vs. American English

British people and American people can always understand each other – but there are a few notable differences between British English and American English

Grammar
Americans use the present perfect tense less than speakers of British English and a British teacher might mark wrong some things that an American teacher would say are correct.

AMERICAN
BRITISH
Did you do your homework yet?
Have you done your homework yet?
I already ate.
I’ve already eaten.

In British English, ‘have got’ is often used for the possessive sense of ‘have’ and ‘have got to’ is informally used for ‘have to’. This is much less common in American English.

AMERICAN
BRITISH
I have two sisters.
I’ve got two sisters.
I have to go now.
I’ve got to go now.

There are a number of other minor grammatical differences.

Vocabulary

There are British words which many Americans will not understand and vice versa. There are also words which exist in both British and American English but have very different meanings.
