Conjunctions connect words or groups of words and show how the words are related. There are three kinds of conjunctions: coordinating conjunctions, correlative conjunctions, and subordinating conjunctions.
1. Coordinating conjunctions link similar words or word groups. There are seven coordinating conjunctions:
for
and
nor
but
or
yet
so
Quick Tip
Use this mnemonic to help you remember the seven coordinating conjunctions: FANBOYS (for, and, nor, but, or, y et, so).
2. Correlative conjunctions also link similar words or word groups, but they are always used in pairs. Here are the correlative conjunctions:
both ...and
either ... or
neither ... nor
not only ... but also
whether ... or

after
as long as
before
since
unless
where
although
as soon as
even though
so that
until
wherever
as
as though
