Usage

Commonly Confused

The suffix -wise is old in the language in adverbs referring to manner, direction, etc.: crosswise; lengthwise. Coinages like marketwise, saleswise, and weatherwise are often criticized, perhaps because of their association with the media: Otherwise—or moneywise, as they were already saying in the motion-picture industry—Hollywood was at the crest of its supercolossal glory. This suffix should not be confused with the adjective wise1 , which appears in such compound words as streetwise and worldly-wise.

Explanation

The adjective wise describes someone who has experience and a deep understanding. Your wise older sister always gives the best advice. When you make a decision based on careful thought and good judgment, you've made a wise choice. If someone calls you a wise guy, though, it's not a compliment: it's likely to be a criticism of your joke at someone else's expense or your rudeness. To wise off (or sometimes, to be wise), has a similar meaning: to talk back or be disrespectful.
