Words with wise?

[Dawood Usmani]

Hi teachers!
How should we write words with "wise" e.g. class wise, subject wise? Are the words used with wise one-word-words or two-word-words?
Best regards!
Dawood

[David L.]

class-wise
subject-wise

Note that while '-wise' may be used in business 'speak', it is considered inelegant English! It would be considered a one-word adverb.

Incidentally, if the word was coined a long time ago there's sometimes no hyphen: clockwise generally doesn't, though there may still be dictionaries that give it one. And very formal words, with modified spelling (?), have no hyphen - the only example I can think of is 'contrariwise' (rarely used - maybe coined by Lewis Carrol [no time to check, I'm afraid]).
