IPA: /ɪmˈpɛkəbl/
KK: /ɪmˈpɛkəbl/
Something that is flawless and perfect, without any mistakes or faults.
Her impeccable taste in fashion always impresses everyone at the event.
Impeccable → It is formed from "in-" (meaning not) and "peccare" (meaning to sin or do wrong). The word "impeccable" means not capable of sinning or being wrong, thus describing something flawless or perfect.
Think of 'not' ('in-') being combined with 'to sin' ('peccare') — this helps you remember that something impeccable is free from flaws or mistakes.
