The Use of Punctuation Marks

If we talk or deliver a speech as one singing a song without pausing, we may not communicate effectively. So when punctuations are correctly observed and employed in the right places when writing, it creates a better understanding of the message that is passed across, as well as verbal communication. Here we shall examine common punctuation marks in our everyday written passages.

l. COMMA (,)

A. Use Commas between items that appear in a Series. Names of persons belonging to the same profession reeled out in a chain or series, should be punctuated with a comma.


(a) A bevy of Girls (with their names) Judith, Mary, Evelyn, Hassanah, Kemi were absent from the class.

(b) Members of the University Disciplinary Committee include Professor Makinde, Engineer Osakhue, Dr. John, Barrister Owushi and Mr. John Obi.

B. Use Commas with coordinating conjunctions (and, or, but, for, yet, so) that join independent clauses.

C. Use Commas between adjectives that, individually, modify the same noun e.g. Tabloids contain unreliable, titillating stories.

(b) Scholarly Journals, on the other hand, require the volume number and year of publication in parentheses

E. Use Commas after long introductory Phrases or Clauses

C. Use Semicolons in compound sentences if the clauses are long and contain Commas thhin them.

  1. PERIODS (.)

A. Use Periods to bring a sentence to an end.

B. Use Periods between related numbers. For example, to separate Act, Scene and Line Number in a play (3.2.6-8). When a Parenthesis is used, employ Period outside the Parentheses thus:( ). That is if the enclosed statement is a complete sentence. Also employ Periods at the end of a Quotation Mark.
