eardrum; tympanum (membrane that separates the outer ear from the middle ear) · kettledrum (large drum with a tunable drumhead) · tympanum (space between the sides of a pediment)
çekim: çoğul tímpanos
köken: Borrowed from Latin tympanum (“drum”), from Ancient Greek τύμπανον (túmpanon, “drum”). Doublet of timbre.
hummock, hillock (small natural elevation of earth, generally smaller than kukkula (“hill”) and larger than kumpare (“knoll”)) · mound (small, rounded, artificial elevation of earth)
çekim: çoğul kummut · tamlayan kummun
köken: From Proto-Finnic *kumpu, from Proto-Uralic *kumpe (“elevation, hillock”), whence also Erzya кумбо (kumbo, “hummock”), Moksha комба (komba, “hump”) and Proto-Samic *kompë. Contains a -u suffix which is not seen in the earlier derivation kumpare. The Finnic root was earlier compared with Proto-Germanic *humpaz (whence English hump), but their similarity must be regarded as coincidental.
köken: màng + nhĩ. The second element is from Chinese 耳 (“ear”), making this a rather unusual formation given how nhĩ is not normally used as a full-fledged morpheme in conjunction with non-Sino-Vietnamese ones. Probably a calque of Chinese 耳膜 (nhĩ mạc). Compare lồi xỉ for another case with similar formation.
