Although we don't specialize too much on grammar, the following is a very useful grammar tip when writing.
Conjunctions A conjunction is a word that "joins". A conjunction joins two parts of a sentence.

Here are some example conjunctions:

Coordinating Conjunctions Subordinating Conjunctions and, but, or, nor, for, yet, so although, because, since, unless 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.
  • Coordinating conjunctions always come between the words or clauses that they join.

  • Subordinating conjunctions usually come at the beginning of the subordinate clause.
