IPA: /kənˈdʒiːniːəlɪti/
KK: /kənˈdʒiːniəlɪti/
The quality of being friendly, pleasant, and agreeable, often because of shared interests or tastes.
Her congeniality made it easy for everyone to feel comfortable at the party.
Congeniality is formed from "con-" (meaning together) and "genus" (from Latin, meaning kind or type) and the suffix "-ality" (meaning the state or quality of). The word describes the quality of being agreeable or compatible with others, as if sharing a common kind or nature.
Think of being 'together' ('con-') in a 'kind' or 'friendly' way ('genus') — that's what congeniality means.
