/ˈtraɪləʊb/
three-lobed
Etymology
'trilobe' originates from the combining elements 'tri-' (from Greek 'tri-' meaning 'three') and New Latin/Latin 'lobe' (from Latin 'lobus', ultimately from Greek 'lobos' meaning 'lobe' or 'pod').
'trilobe' arose as a modern English/Scientific formation by combining 'tri-' + 'lobe'; related formations such as Latin 'trilobus' and English adjectives 'trilobed'/'trilobate' appear in botanical and anatomical Latin/English usage from the 18th–19th centuries before the simple noun/adjective 'trilobe' entered specialized usage.
Initially formed to denote 'having three lobes' in technical descriptions, its meaning has remained essentially the same and is used descriptively in anatomy and botany.
