IPA: //əˌklaɪ.məˈteɪ.ʃən//
KK: /ˌæk.lɪˈmeɪ.ʃən/
The process of adjusting to a new environment or situation, especially in terms of temperature, climate, or other conditions.
The acclimation of the plants to the new climate took several weeks.
Acclimation is formed from "ac-" (meaning to) and "climare" (meaning to climb or to slope). The word refers to the process of adjusting to a new climate or environment, as if one is climbing to a new level of adaptation.
Think of 'climbing' ('climare') to a new 'level' of comfort in a different environment when you hear 'acclimation'.
