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?

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

The pronunciation of "upload" can vary slightly depending on the dictionary and region. Here are the different pronunciations provided in the dictionaries you mentioned:

1. Collins Dictionary: /ʌpˈləʊd/
2. Cambridge Dictionary: UK /ʌpˈləʊd/, US /ˈʌpˌləʊd/
3. Webster Dictionary: \(ˌ)əp-ˈlōd, ˈəp-ˌ\
4. Webster's Learner's Dictionary:
- verb: /ˌʌpˈloʊd/
- noun: /ˈʌpˌloʊd/
5. Oxford Dictionary:
- verb: /ʌpˈləʊd/
- noun: /ˈʌpləʊd/

In general, when "upload" is used as a verb, the primary stress is often on the second syllable (/ʌpˈləʊd/). When used as a noun, the primary stress can be on the first syllable (/ˈʌpˌləʊd/), although it can vary. The difference in stress between British English (BE) and American English (AE) is not always consistent, as it can vary depending on the specific dialect or individual speaker.

The pronunciation of "upload" can vary depending on the dictionary and the region in which it is used. However, I can help explain the general patterns and differences.

When "upload" is used as a verb, the primary stress is typically placed on the second syllable. This pronunciation is common in British English (BE) and some American English (AE) dialects. In BE, the primary stress is indeed on the second syllable, pronounced as /ʌpˈləʊd/. In AE, it can vary, but /ˈʌpˌloʊd/ is another accepted pronunciation for the verb form.

When "upload" is used as a noun, the primary stress is often placed on the first syllable. This pronunciation is also common in BE and some AE dialects. In BE, the primary stress is on the first syllable, pronounced as /ʌpˈləʊd/. In AE, /ˈʌpˌloʊd/ can be used for the noun form.

Here are the pronunciations provided by the dictionaries you mentioned:

1. Collins: /ʌpˈləʊd/
2. Cambridge: verb - UK: /ʌpˈləʊd/, US: /ˈʌpˌləʊd/
3. Webster: verb - /ˌʌp-ˈlōd, ˈʌp-ˌ/, no specific noun pronunciation given
4. Webster's Learner's Dictionary: verb - /ˌʌpˈloʊd/, noun - /ˈʌpˌloʊd/
5. Oxford: verb - /ʌpˈləʊd/, noun - /ˈʌpləʊd/

Based on these pronunciations, the most common pattern is to stress the second syllable when "upload" is used as a verb, and stress the first syllable when it's used as a noun. However, it's worth noting that pronunciation can vary among speakers and regions, so some individual preferences or local dialects may differ.
