The Semi Colon
The semicolon is somewhere between a weak full stop and a strong comma and used to join phrases and sentences without having to use a conjunction (and, but etc.) where the phrases or sentences are thematically linked but independent.
Look at this example.
- Many great leaders; Churchill, leader of Britain during the Second World War; Alexander, the great Roman Emperor and general; and Napolean, the brilliant French general, had great strengths of character which were useful when their countries were at war but also great weaknesses which did not serve them so well in times of peace.
Notice how the semicolon works with the comma to enclose the connected phrases while the whole forms one logical sentence.
