Language is like a train in motion and the marks of punctuation are like its wayside stations. Punctuation is an art. It is the art of dividing a piece of writing by points or marks to make its sense clear. Even while speaking, we pause or stop at certain places for the sake of clarity. In written composition, these pauses or stops are indicated by means of certain signs which are called marks of punctuation. These marks of punctuation divide a passage into sentences and clauses and bring out their relation with one another. They tell us where to pause and for how long. The following are the principal marks of punctuation:

4. Colon (:)
5. Sign of Interrogation (?)
