IPA: /ˌeɪpəˈlɪtɪsɪzəm/
KK: /əˌpɒlɪˈtɪsɪzəm/
A lack of interest or involvement in political affairs or issues.
His apoliticism made him indifferent to the upcoming elections.
Apoliticism → It is formed from "a-" (meaning without) and "politics" (from Greek "politikos", meaning of or relating to citizens or the state). The word "apoliticism" refers to a state of being without political interest or involvement.
Think of 'a-' meaning without, and 'politics' relating to citizens or the state — so apoliticism means being without interest in politics.
