Some two-syllable words are "ancient," "bacon," "hockey" and "table." A syllable is a unit of organization for a sequence of sounds that relate to speech. Every word has one or more syllables.
The word water also has two syllables: "wa" and "ter." Syllables are often referred to as the "building blocks" of words. Syllables influence many aspects of spoken languages, including poetic meter and stress patterns. They also heavily affect prosody, which entails certain features of speech, such as the presence of sarcasm or irony.
People began writing with syllables hundreds of years before letters were created. Tablets dating to the year 2800 B.C. contain written syllables. Some people consider the change from pictograms to syllables as the most important advancement in the history of written language.
Words that consist of single syllables are called "monosyllable." Words that contain two syllables are called "disyllable." "Trisyllable" refers to words with three syllables and "polysyllable" is a term for any words with more than one syllable, including words with more than three syllables.
English allows complex syllables that begin with up to three consonants that form a cluster. Other languages, such as Japanese, allow for only one consonant at the beginning of a syllable.
