Main Clauses

You can use a semicolon instead of a full stop between two main clauses when:

  • the second clause restates the first
    There was a flood in April last year; it rained non stop for two weeks.
  • the meaning of the two clauses is connected
    My sister has three children; the children all have brown hair.
  • instead of using a conjunction (and, because, so etc.) to separate the clauses
    The rain stopped; the sun came out.

Use a semicolon between two main clauses which are separated with a conjunction (and, or, but etc.) when a comma is used in one or both of the main clauses.

At work, we often eat breakfast together; and sometimes we also drink champagne.

Use a semicolon between two independent clauses when the second one starts with a conjunctive adverb (e.g. however, therefore, nevertheless, moreover, furthermore, still, instead, otherwise, thus) or a transitional words and phrases (on the other hand, in addition, in other words, for example etc).
