“Advices” and other traps
“Advice” is uncountable in modern English, so “advices” is wrong in everyday writing: say “some advice” or “pieces of advice”. “Adviced” is never correct; the past tense is “advised”.
The same c/s pattern shows up in British English with practice (noun) and practise (verb), and licence/license. In American English, practice is used for both.
Adviser or advisor?
Both spellings are correct. “Adviser” is more common in British English and in AP style; “advisor” is common in American academic and business titles. Pick one and stay consistent.
