How is tentamine pronounced?

"Tentamine" is not a word in the English language, so it's difficult to say how it would be pronounced. It might be a misspelling of "tentamine," which is a word in Latin, but it is not a common word in English.

If "tentamine" is intended to be a misspelling of "tentamen," then the pronunciation would be:

* ten-tah-men

The stress is on the first syllable, and the "a" in the second syllable is pronounced like the "a" in "cat."

If you can provide more context about where you encountered this word, it might be easier to determine the correct pronunciation.
