Semicolon

Semicolon

The semicolon is stronger than a comma, but weaker than a full stop. Semicolons are not as common as full stops or commas. Don’t write capital letters after semicolons, unless writing a name or proper noun.

Main Clauses

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

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

Example:
James had, to put it mildly, a lot of problems; and even his best friend couldn’t help him.
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).

Example:
He didn’t feel well; in fact, he had a very high temperature.
Darcy doesn’t normally eat sweets; however, he makes an exception on his birthday.
I didn’t know Lisa was pregnant; otherwise, I would have said congratulations.

Lists

Use a semicolon in lists when items in the list already contain a comma.

Example:
We have business partners in Edmonton, Canada; Waterford, Ireland; Brisbane, Australia; and Durban, South Africa.
Last week I bought three cushions: a red, yellow and green one; a pink, purple and orange one; and a white one.

Use a semicolon when listing phrases or clauses which are longer or more complex.

Example:
You may use the communal kitchen on the condition that you clean up after yourself; that you are respectful with other hostel guests; that you label all food stored in the fridge; and that you do not remove any supplies from the kitchen/dining area.
