Could you please confirm for me whether my understanding is correct about the pronunciation of the ending -est in superlative, for example: shortest, farthest, biggest,...
- -est is pronounced as /ɪst/ in American English (ref: https://www.youtube.com/watch?v=UfV5Tq3YMGc)
- -est is pronounced as /ɛst/ in British English (ref: https://www.youtube.com/watch?v=VXoiOzQCqxg )
- -est is pronounced as /əst/ when people don't pronounce seriously in casual situation. We use schwa sound /ə/ for unstressed syllables
However, if in American English, -est is really pronounced as /ɪst/, how American people pronounce the words best? I have never heard anyone pronounces the word best as /bɪst/.
