IPA: /ɑːrˈtɪk.jʊ.leɪ.tər/
KK: /ɑrˈtɪk.jə.leɪ.tər/
A part of the body used in speech, like the tongue or lips, that helps produce sounds.
The tongue is an important articulator in forming words.
Articulator → It is formed from "articulare" (meaning to divide or to separate) and the suffix "-tor" (meaning one who). An articulator is one who divides or separates sounds, particularly in speech.
Think of someone who 'divides' ('articulare') sounds clearly — that's what an articulator does.
