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.

Dependant

In the ordinary British usage of today “dependant” is a noun meaning “a person who depends on another for support, etc.”. “Dependent” is an adjective meaning relying on or subject to something else. Dependants are dependent on the person whose dependants they are.
