In everyday speech say 「変わる」 or 「なる」 instead, and use 「転じる」 for a turn or shift in direction; the opposite of changing is 「そのまま」. Among the nouns, 「変化」 is the general all-purpose word; others are narrower, such as 「変動」 for fluctuation, 「変遷」 for change over time and the casual 「チェンジ」 for switching or swapping.
