IPA: /ˈrɛnɪɡeɪd/
KK: /ˈrɛnɪˌɡeɪd/
A person who deserts and betrays an organization, country, or set of principles.
He was considered a renegado for leaving the group and sharing their secrets.
Renegado is derived from the Spanish word 'renegado', which comes from the Latin 'renegare' (meaning to deny or reject). The Latin root is formed from 're-' (meaning back) and 'negare' (meaning to deny). Thus, 'renegado' refers to someone who has denied or rejected their faith or allegiance.
Think of someone who has 'denied' ('negare') their previous beliefs or loyalties, as 'renegado' means a person who has turned their back on their former faith.
