A conjunction is used to link
words, phrases, or clauses.
Two types of conjunctions are
coordinate conjunctions (and,
or, nor, but, etc.) and
subordinate conjunctions
(although, since, because,
when, before, etc.).

Coordinate conjunctions may link
similar ideas (and, not only. but also),
opposite or contradictory ideas (but),
or choices (either.. .or, neither... nor).
Pay attention to the meaning of the
INCORRECT [It is efficient or

CORRECT It is efficient and

INCORRECT [We can take
either a morning flight but an
early afternoon flight.]
CORRECT We can take
either a morning flight or an
early afternoon flight.

Subordinate conjunctions show
different kinds of relationships
between two clauses. They may
show cause and effect (because, so,
as, since), time (when, while, after,
before, until, as soon as), condition
(if, unless), or a contradiction (even
though, although). Again, pay
attention to the meaning of the

INCORRECT [The machine shut off
even though the power went off.]
CORRECT The machine shut off
when the power went off.
INCORRECT [I couldn’t call them
until I don’t know their phone
CORRECT I couldn’t call them
because I don’t know their phone
