Avoid being enslaved by seven writing myths. Here are those seven non-rules imposed on writers that can be safely discarded:
(1) You must not start a sentence with ‘but’, ‘so’, ‘because’, ‘and’, and ‘however’.
(2) You must not put a comma before ‘and’. A comma before ‘and’ may, in fact, help the reader to see how the sentence is constructed, or put a pause exactly where you want it.
(3) You must not end a sentence with a preposition.
(4) You must not split your infinitives - If you think a sentence will be more emphatic, clear or rhythmical, split your infinitive – there is no reason in logic or grammar for avoiding it.
(5) You must not write a one-sentence paragraph. If you can say what you want to say in a single sentence that lacks a direct connection with any other sentence, just stop there and go on to a new paragraph; there’s no rule against it.
(6) You should write as you speak.
(7) You should test your writing with a readability formula.
