Pronunciation: /əsˈfɪksieɪt/

Definitions

3. To deprive a person or animal of oxygen, causing them to choke or die

Etymology: Asphyxia came into English from Greek "asphyxia," meaning "stopping of the pulse," built from "a-" (not) and "sphyxis" (pulse). The original sense was about the heartbeat failing, not simply the lack of breath. The Greek root reflects an older understanding that a stopped pulse and stopped breathing went together. Asphyxiate is a much later formation: English took the noun and added the verb-forming ending "-ate," a pattern that turns nouns into verbs (as in "dominate" or "hyphenate"). So the verb is a native English construction built on a borrowed Greek noun, rather than a word inherited directly from classical times. The pairing is a reminder that many English verbs ending in "-ate" were made this way, taking a learned noun from Greek or Latin and giving it a verb ending that the original language never had.
