In-thu-see-ast or en-thu-see-ist?

En…Pronounced “ehN”
And your details could use clarification “I used to always use the former but have recently switched to the former”

Oh stupid mistake I suppose I meant the latter to be “latter”

The latter. Enthusiast. But en-thu-see-AST-ic.

The latter.

An-thu-see-ast.

@erichw1504 you southern FIBbers get is all wrong;P

Enthusiast. Pronounced: ehn-thoo-zee-ust, with your spoken emphasis on “thoo”.

@WillWorkForChocolate or with your spoken emphasis on “zee”.

En-thue-zee-ast

I say /ɛnˈθuziˌɪst/ (your second example), but according to the dictionary, /ɛnˈθuziˌæst/ (your first example) is perfectly acceptable and is actually the first pronunciation given.

En.

Eeeeeen- thus- e- ist
