IPA: /ɪmˈpiːəs/
KK: /ˈɪm.pi.əs/
Not showing respect or reverence, especially towards religious beliefs or sacred things.
His impious remarks about the ceremony shocked everyone present.
Impious → It is formed from "in-" (meaning not) and "pius" (from Latin, meaning dutiful or pious). The word "impious" describes someone who is not dutiful or lacking in reverence, especially towards God or sacred things.
Think of 'not' ('in-') being combined with 'dutiful' ('pius') — that's why impious means lacking in duty or reverence.
