Initially in cytology from German Syndesis, coined by Valentin Häcker in 1904 from Ancient Greek σύνδεσις (súndesis, “binding, joining”), from συνδεῖν (sundeîn, “to join, to bind”) + -σῐς (-sis, “-sis: forming nouns”), from σῠν- (sun-, “together”) + δεῖν (deîn, “to bind, to tie”). Equivalent to syn- + -desis.
syndesis (usually uncountable, 複数形 syndeses)
