Neophyte

ˈniːəˌfaɪt

noun

a person who is new to a subject, skill, or belief

The word 'neophyte' is often used to describe someone who is a beginner or novice in a particular field or belief system. It comes from the Greek words 'neos', meaning 'new', and 'phytos', meaning 'planted' or 'a beginner'.

Full of the neophyte's zeal for vegetarianism I decided to start a vegetarian club in my locality, Bayswater.
