An English professor wrote the words:

" A woman without her man is nothing " on the chalkboard

           and asked his students to punctuate it correctly..


            All of the males in the class wrote :
                  "A woman, without her man, is nothing."

            All the females in the class wrote :
                  "A woman: without her, man is nothing."  

FULL STOP

1.     One of the commonest mistakes of students is using full stop before conjunctions such as but, yet, and, so, while, because:

        X The child started crying. Because he lost his toy.

        Instead it should read:

√ The child started crying because he lost his toy.

APOSTROPHE

        1.     One typical mistake is forgetting to use apostrophe where necessary;

                in possessives:

                         X mens toilet

                         √ men's toilet
