well-established
UK: ˌwel ɪˈstæblɪʃt | US: ˌwel əˈstæblɪʃt
adj. 1. Firmly and securely founded or settled; having a long history of success or reliability.
adj. 2. Widely recognized or accepted due to enduring presence or quality.
The word combines "well," from Old English wel (meaning "in a good way"), with "establish," derived from Latin stabilire (to make stable), via Old French establir. The suffix "-ed" marks it as a past participle, giving the sense of something that has been firmly set up over time. The term reflects a logical progression from the act of founding (establish) to the enduring state of being recognized or stable (well-established).
