ENGL1010 Composition IFor is seldom used in American English as a conjunction except in very formal writings. Usually the second sentence is changed into a dependent clause using because.
I stayed home because I was sick.
Nor and Or are also seldom used, and when they are, most people use them correctly.
Yet is frequently misused as a substitute for but. Yet should only be used for an unexpected contrast.
So can be tricky in a sentence. If the two clauses being connected are cause and effect, use so with a comma to join the clauses.
Example: I was sick, so I stayed home.
If so is used to connect something to a reason for that thing and if the word that can be placed after the word so, then do not place a comma before so. In this case, the second clause is a dependent clause.
Example: I stayed home so (that) I could watch television.
And and But are the most common conjunctions used. If they are used to connect two words or phrases, however, a comma should not come before the conjunction.
Example: I like ice cream and cake.
Example: I like asparagus but hate brussel sprouts.
