there is two. a good way to count out sylables is to put your hand under your chin and as you say the word count how many times your jaw moves.
How many syllables does unfamiliar have?
4, un, fah, mill, yer. The last syllable should not be broken into e-yar in American English.
Does poured have two syllables or one?
One syllable. It is important to remember that syllables are identified based on how they sound, not on how they are spelled. As a general rule, you may consider a syllable to be a part of a word in which the sound is uninterrupted and is distinct from the other parts.
The word "poured" is a single-syllable word because when it is spoken, the sound of the word is unobstructed - i.e., the sound flows from beginning to end without interruption from harsh sounding consonants. A few examples of single-syllable words that end in -ed include loved, liked, worked, forced, looked, ripped, trimmed, wrapped, cured, grieved, and walked.
In contrast, the word "tested" is a two-syllable word because the e in -ed is emphasized when spoken, resulting in an interruption to the flow of the word's pronunciation similar to the interruption that occurs when pronouncing compound words. A few examples of two-syllable words include hated, acted, tasted, added, doted, fainted, parted, cited, sorted, and mended.
