not forming a lineage

Etymology
Etymology Information

'nonphyletic' originates from Modern English, specifically the prefix 'non-' (from Latin 'non', meaning 'not') combined with 'phyletic' which ultimately derives from Greek 'phylē' (φύλη) meaning 'tribe' or 'race' via New Latin/technical formation 'phyletic'.

Historical Evolution

'nonphyletic' developed in scientific usage by attaching the negative prefix 'non-' to 'phyletic' (itself formed from Greek roots and New Latin usage). The hyphenated form 'non-phyletic' appears in 20th-century biological literature and later crystallized as the concatenated modern form 'nonphyletic'.

Meaning Changes

Initially built simply to mean 'not belonging to a phyle/tribe' from classical roots, in modern biological contexts it evolved to mean 'not forming a single evolutionary lineage (not a clade)'.
