What does evangelizer mean?
An evangelizer is a person who evangelizes — someone who actively and enthusiastically promotes a belief, cause, or product in the hope of winning others over to it. The word derives from 'evangelize', which ultimately traces back through Late Latin and Greek roots meaning 'to bring good news'. Historically it described those who spread religious doctrine, particularly the Christian gospel, but in contemporary English it is used far more often in secular contexts: companies hire 'product evangelizers' and 'technology evangelizers' whose job is to generate excitement and adoption among customers and developers. The term implies fervour and conviction — an evangelizer does not merely endorse something but campaigns for it with missionary-like dedication. Depending on context it can sound admiring, suggesting passion and persuasive skill, or faintly critical, suggesting pushiness. It remains a vivid alternative to blander words like 'advocate' when genuine zeal is meant.

Etymology of evangelizer
'Evangelizer' derives from the verb 'evangelize', which entered English around the early 17th century via ecclesiastical Latin 'evangelizare', itself borrowed from Greek 'euangelizesthai' ('to bring good news'). The Greek combines 'eu-' (good) with 'angelos' (messenger), the same root that gives us 'angel' and 'gospel' — the latter being a calque of 'euangelion' into Old English as 'good spell'. The agent suffix '-er' produced 'evangelizer' for one who performs the action.

The purely religious sense is less common today than 'evangelist'. Slightly formal in register.
