Quadricipital is spelled with four syllables, /kwɒd.rɪˈsɪp.ɪ.təl/. The first syllable is pronounced with the consonant blend /kw/, followed by the short vowel /ɒ/. The second syllable has the vowel sound /ɪ/ and the consonant sound /r/. The third syllable contains the short vowel /ɪ/ and the consonant sound /p/. The final syllable has the stress, and is pronounced with the vowel sound /ɪ/ followed by the consonant sound /t/ and the unstressed vowel schwa /əl/.

The word quadricipital does not have an established etymology. It appears to be a combination of quadri- meaning four and cipital which could be speculated to come from the Latin word caput meaning head. However, it should be noted that quadricipital is not a standard term in English. The correct medical term for the muscle group at the front of the thigh is quadriceps.
