In the manner or direction of a funnel; arranged or moving in a funnel-like pattern that narrows to a point.
Compound adverb from 'funnel' plus '-wise' (in the manner of, or concerning), an archaic but still valid suffix for creating directional or manner adverbs.
The '-wise' suffix is old-fashioned but still appears in words like 'clockwise' and 'lengthwise'—it's one of English's oldest ways to describe direction or manner!
