Impoliiticly → It is formed from "im-" (meaning not) and "politic" (from Latin "politicus", meaning of or relating to citizens or government) and "-ly" (meaning in a manner). The word "impoliticly" means in a manner that is not wise or prudent in political matters.
Think of 'not' ('im-') being combined with 'political' ('politic') to remember that 'impoliticly' means acting in a way that is not wise in political situations.
