Question

I checked the pronunciation of 'upload' in some dictionaries.
I could find several ones.
How do we pronounce 'upload'? When upload is used as a verb, do we put the primary stress on the second syllable? Do we put the primary stress on the first syllable when 'upload' is used as a noun? Some dictionaries seem to say that. In another dictionary, 'upload' is used as a verb, and the primary stress was on the first syllable. Which one do we have to use? When 'upload' is used as a verb, in BE, the primary stress is on the second syllable, while in AE, the primary stress is on the first syllabe? Am I right?

Answer 1

Notice the little mark that looks like an apostrophe (') after the first syllable in most of these? That's there to indicate that the first syllable is to be stressed or pronounced a bit more loudly than the other syllable.

When used as a verb, though, in its past tense, the second syllable should be stressed: up load' ed
