See Wood, Suggestions to Authors, pp. 68–71, and Quiller-Couch, The Art of Writing, pp. 103–106.

Certainly. Used indiscriminately by some writers, much as others use very, to intensify any and every statement. A mannerism of this kind, bad in speech, is even worse in writing.

Character. Often simply redundant, used from a mere habit of wordiness.

Acts of a hostile character Hostile acts

Claim, vb. With object-noun, means lay claim to. May be used with a dependent clause if this sense is clearly involved: “He claimed that he was the sole surviving

heir.” (But even here, “claimed to be” would be better.) Not to be used as a substitute for declare, maintain, or charge.

Clever. This word has been greatly overused; it is best restricted to ingenuity displayed in small matters.

Compare. To compare to is to point out or imply resemblances, between objects regarded as essentially of different order; to compare with is mainly to point out differences, between objects regarded as essentially of the same order. Thus life has been compared to a pilgrimage, to a drama, to a battle; Congress may be compared with the British Parliament. Paris has been compared to ancient Athens; it may be compared with modern London.

Consider. Not followed by as when it means “believe to be.” “I consider him thoroughly competent.” Compare, “The lecturer considered Cromwell first as soldier and second as administrator,” where “considered” means “examined” or “discussed.”

Data. A plural, like phenomena and strata.

These data were tabulated.

Dependable. A needless substitute for reliable, trustworthy.

Different than. Not permissible. Substitute different from, other than, or unlike.

Divided into. Not to be misused for composed of. The line is sometimes difficult to draw; doubtless plays are divided into acts, but poems are composed of stanzas.

Don't. Contraction of do not. The contraction of does not is doesn't.

Due to. Incorrectly used for through, because of, or owing to, in adverbial phrases: “He lost the first game, due to carelessness.” In correct use related as predicate or as modifier to a particular noun: “This invention is due to Edison;” “losses due to preventable fires.”

Folk. A collective noun, equivalent to people. Use the singular form only.

Effect. As noun, means result; as verb, means to bring about, accomplish (not to be confused with affect, which means “to influence”).
