I wonder how an American pronounces…
Nurse to patient:
You look sick. Let’s take your temperature.
You’re really sick. You have a very high temperature. = You have a fever.
We write 4 syllables: tem-per-a-ture
We say 3 syllables: /ˈtɛm-prə-t͡ʃɚ/
Why do we say only 3 syllables?
BecauseR is king of the consonants.
R can make certain vowels disappear completely.
This video has a list of words with R + disappearing vowel.
I took some medicine, my temperature is back to normal now and I feel great.
