IPA: /ɪmˈpɒlɪsi/
KK: /ɪmˈpɑlɪsi/
The condition of being unwise or not showing good judgment in a situation.
His impolicy in handling the negotiations led to a breakdown in trust.
Impolicy is formed from "im-" (meaning not) and "policy" (from Greek "politeia", meaning citizenship or government). The word refers to actions that are not wise or prudent in the context of governance or policy-making.
Think of 'not' ('im-') being applied to 'policy' — this helps you remember that 'impolicy' means actions that are unwise or imprudent in governance.
