Consensus

The spelling “concensus” is wrong. A “consensus” is the result of common consent; it has nothing to do with censuses. This is an overused fashionable word for the moderate undisputed middle ground in politics. It can sometimes be replaced by the simpler “agreement”.

Centre

Traditionally things centre ON, UPON or IN other things, though an institution may be centred at a place. Many people still dislike the combinations “centre around” and “centre about”, as in “many legends centre around this holy shrine”.

Capitalise

Replace this vogue word by “draw upon” or “profit by” if you can, as in “to capitalise on her legal experience”.

Bona Fides

It means “sincerity”, good standing. If you use this Latin expression, use it with a singular verb, as in “his bona fides was questioned”. “Bona fide”, which looks like the singular form, is an adjective not a noun, as in “a bona fide query”.

Appraise, Apprise

To “appraise” is to form a judgement about the value of something. You can appraise a candidate for a job by interviewing him or her, or a race-horse from his appearance in the paddock. It is sometimes confused with “apprise”, which means inform, and is better replaced by “inform” in any case.

Around

It is still somewhat of an Americanism to use “around” for “about” or “roughly”, as in “around 60°”. Avoid the practice.
