Regional and archaic verb forms kenned and kenning are outside the retained scope. Commonness: uncommon (editorial estimate; not a corpus frequency statistic). Legacy lexical fields mirror sense 1; numbered fields keep each relevant meaning separate. Research distinction: Direct dictionary reading: noun range of perception/understanding/knowledge and range of vision/sight. Verb archaic see and Scottish/dialect recognize/know, kenned/kenning. Current understanding noun is primary; older physical sight retained; regional verb scope flagged, not added as universal contemporary usage. Individual usefulness checked for a precise literary, narrative, dialogue or critical function. Definitions and examples are original; commonness is an editorial estimate. Mood and intensity apply only to inherent qualities of the specific sense. Writing functions: limits of personal understanding, an older literary way to name visual reach.
