-aesthesia-esthesiacomb. form
Primary stress is attracted to the second syllable of this combining form and vowels may be reduced accordingly.
Origin: A borrowing from Greek. Etymon: Greek -αισθησία.
Etymology: < ancient Greek -αισθησία (in e.g. ἀναισθησία anaesthesia n., δυσαισθησία dysaesthesia n.) < αἴσθησις aesthesis n. + -ία -ia suffix1. Compare post-classical Latin -aesthesia (formations in which are found from at least the late 18th cent., e.g. pseudaesthesia).Attested earliest in the early 18th cent. in the Greek loans dysaesthesia n. and anaesthesia n. (perhaps both via post-classical Latin), and subsequently in pseudaesthesia n. at pseudo- comb. form 2, an early 19th-cent. adaptation from post-classical Latin. Formations within English are found from at least the first half of the 19th cent., e.g. oxyaesthesia n. at oxy- comb. form1 1. Combining with first elements of Greek origin.
