Hello File Leech, welcome to English Forums,
I would say that a syllable is a word or a part of a word that consists of one vowel or diphthong sound, with 0–5 consonant sounds on each side.
e.g.
help: 1 vowel sound
![Email [E]](/emoticons/emotion-57.gif)
= 1 syllable
what's: 1 vowel sound
![Angel [A]](/emoticons/emotion-13.gif)
= 1 syllable
a: 1 vowel sound
![Angel [A]](/emoticons/emotion-13.gif)
= 1 syllable
syllable = 3 vowel sounds [y, a, e] = 3 syllables
Don't forget to ignore any silent vowels.
You can find out how many syllables there are by looking the word up in a dictionary. Each dictionary has its own method of showing syllables, which will be explained at the front. For instance, Merriam-Webster online puts dots between the syllables, like this:
syl·la·ble
Count the dots and add one, and you have the number of syllables.
