How do you say Tampa in spanish?

To get the English pronunciation from a Spanish-speaker, write:

'tami', with an accent over the 'a'.

To spell the Word 'Tammy' using the names of the Spanish letters:

T - te (tay)

A - a (ah)

M - eme (Emmay)

M - ditto

Y - y griega (ee gree-AY-gah)

After the letters, the above shows the Spanish name for the letter, then the way this name is pronounced in English. NB 'ditto' means 'eme' etc., because the letter is repeated.
