As noun, often loosely used in perfunctory writing about fashions, music, painting, and other arts: “an Oriental effect;” “effects in pale green;” “very delicate effects;” “broad effects;” “subtle effects;” “a charming effect was produced by.” The writer who has a definite meaning to express will not take refuge in such vagueness.

Etc. Equivalent to and the rest, and so forth, and hence not to be used if one of these would be insufficient, that is, if the reader would be left in doubt as to any important particulars.

Feature. Another hackneyed word; like factor it usually adds nothing to the sentence in which it occurs.

As a verb, in the advertising sense of offer as a special attraction, to be avoided.

Fix. Colloquial in America for arrange, prepare, mend. In writing restrict it to its literary senses, fasten, make firm or immovable, etc.

He is a man who. A common type of redundant expression; see Rule 13.

He is a man who is very ambitious.	He is very ambitious.
Spain is a country which I have always wanted to visit.	I have always wanted to visit Spain.
