The Spanish word 'convivio' meaning 'feast' or 'banquet' comes from the Latin word 'convivium', which had the same meaning. The Latin word was formed by combining two elements: the prefix 'con-' meaning 'with' or 'together', and the verb 'vivere' meaning 'to live'. So literally, a 'convivium' was a gathering where people 'lived together' or shared life and food together in a festive setting.

This word is related to several common Spanish words that share the root 'viv-' from Latin 'vivere'. Some examples include 'vivir' (to live), 'vivo' (alive), and 'convivir' (to live together, coexist). The connection between 'convivio' and these words reflects how sharing a meal was seen as a fundamental way of living together and building community.

In English, we can find related words that come from the same Latin roots. 'Convivial' means 'friendly, lively, and enjoyable' and often describes social gatherings, while 'vivid' (from Latin 'vivere') means 'full of life' or 'bright'. The word 'survive' also contains the same root 'viv-', literally meaning 'to live beyond' or 'to live on'.
