- aff. use a suffixal use of wise II in adverbs denoting manner, position, direction, reference, etc.:clockwise; edgewise; marketwise; timewise[/ex]•usage: 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 news and entertainment media: Moneywise, as they were already saying in the motion-picture industry, Hollywood was at its peak. This suffix should not be confused with the adjective wise I, which appears in such compounds as streetwise and worldly-wise.
