More about convivial
Convivial “friendly, agreeable” comes from Latin convīvium “feast,” which is based on the verb convīvere “to live together, dine together.” The prefix con- “with, together” may also appear as co-, col-, com-, or cor- depending on the letter that follows, as in coincidence, colleague, comfortable, and correct, respectively. The verb vīvere “to live” and its adjective equivalent, vīvus “alive,” are the source of vivacious, vivid, revive, and survival. Of the same origin is the Latin noun vīta “life,” which is the root of vital and vitamin. Convivial was first recorded in the 1660s.
