IPA: /əˈkaʊntəbl/
KK: /əˈkaʊntəbl/
This word describes someone who is responsible for their actions and must explain them to others. It means being answerable for what you do.
As a manager, she is accountable for her team's performance.
Accountable → It is formed from "account" (from Old French *acont*, meaning to count or to render a report) and "-able" (meaning capable of or worthy of). The word "accountable" means capable of being counted on or responsible for one's actions.
Think of being able to 'render a report' ('account') and being 'capable of' ('-able') taking responsibility — that's what accountable means.
