Pronounce "default"

[Pleonast]

@markn_1

It’s common in English for a two syllable word to have the accent on the first syllable when it is used as a noun and on the second when it is used as a verb; for example, “permit”, “record”, “addict”, “refill”, “recoil”, etc. (Long list on Wikipedia). So it would be expected that “default” would have a first syllable accent as a noun (“That procedure is the default”), and a second syllable accent when used as a verb (“He is going to default on his loan.”). To me the ambiguous cases are when it is used as an adjective, and in such cases neither pronunciation seems wrong to me.

Yep for me. If a noun or adjective, stress on first syllable. If verb, on second.
