We often "contract" or shorten words in English. For example, we may say "he's" instead of "he is". Note that we usually insert an apostrophe (') in place of the missing letter or letters in writing. Here are some example sentences:

• I haven't seen him. (I have not seen him.)
• Who's calling? (Who is calling?)
• They're coming. (They are coming.)

We do this especially when we speak. We do not contract words so much in writing

These pages show the most common contracted forms.

A prefix is placed at the beginning of a word to modify or change its meaning. This is a list of the most common prefixes in English, together with their basic meaning and some examples. You can find more detail or precision for each prefix in any good dictionary. The origins of words are extremely complicated. You should use this list as a guide only, to help you understand possible meanings. But be very careful, because often what appears to be a prefix is not a prefix at all. Note also that this list does not include elements like "auto-" or " bio-", because these are "combining forms", not prefixes.

A conjunction is a word that "joins". A conjunction joins two parts of a sentence.

Here are some example conjunctions:

We can consider conjunctions from three aspects.

Form

Conjunctions have three basic forms:

• Single Word
  for example: and, but, because, although
  
  
• Compound (often ending with as or that)
  for example: provided that, as long as, in order that
  
  
• Correlative (surrounding an adverb or adjective)
  for example: so...that

Function

Conjunctions have two basic functions or "jobs":

• Coordinating conjunctions are used to join two parts of a sentence that are grammatically equal. The two parts may be single words or clauses, for example:
  - Jack and Jill went up the hill.
  - The water was warm, but I didn't go swimming.
  
  
• Subordinating conjunctions are used to join a subordinate dependent clause to a main clause, for example:
  - I went swimming although it was cold.

Position

• Coordinating conjunctions always come between the words or clauses that they join.
  
  
• Subordinating conjunctions usually come at the beginning of the subordinate clause.

In this lesson we will look in more detail at:

• Coordinating Conjunctions
• Subordinating Conjunctions

Irregular Adjectives (comparative, superlative)

The regular way to make comparative/superlative adjectives is to add -er/-est or to use more/most. A small number of adjectives, however, are irregular and some of these can be regular or irregular. The most important ones are listed here:
