Usage notes

Primary category: academic / formal / analytical. Lexical Type: Word. Forms: Usually uncountable; plural mereologies for distinct part-whole theories. Commonness: uncommon (editorial estimate; not a corpus frequency statistic). Legacy lexical fields mirror sense 1; numbered fields keep each relevant meaning separate. Research distinction: MW verifies formal part-whole and overlap theory; SEP confirms scope. Plural mereologies is for alternative theories, not ordinary pieces. Writing functions: analysis, conceptual distinction.
