antapexes
|an-ta-pex-es|
/ænˈtæpɛksɪz/
(antapex)
point opposite the apex
Etymology
'antapex' originates from the Greek prefix 'anti-' (meaning 'against, opposite') combined with Latin 'apex' (meaning 'summit, tip').
'antapex' was formed in modern scientific English by joining 'anti-' and 'apex' (used in 19th-century and later astronomical contexts), and the regular English plural 'antapexes' (or the Latin-style 'antapices') developed subsequently.
Initially and historically it meant 'a point opposite the apex'; this core meaning has been retained in modern usage, especially in astronomy.
