Question

when do we use pronounce​

Answer 1

Normally, we pronounce the with a short sound (like "thuh"). But when the comes before a vowel sound, we pronounce it as a long "thee". When we wish to place emphasis on a particular word, we can use "emphatic the" [thee], whether or not the word begins with a consonant or vowel sound.
