How many Syllables are in sprite?
'Sprite' has one syllable.
In English, a good rule of thumb is that there is one syllable per audible vowel sound. So in 'sprite', only the 'i' is audible. (The 'e' is silent, though it influences the pronunciation of the 'i'.) Rare exceptions to this are words like 'rhythm', which is pronounced like a 2-syllable word: 'rhyth-m'.
