In phonology, apocope (/əˈpɒkəpi/ ə-POCK-ə-pee) is the omission (elision) or loss of a sound or sounds at the end of a word. While it most commonly refers to the loss of a final vowel, it can also describe the deletion of final consonants or even entire syllables.
For instance, in much spoken English, the t in the word don't is lost in the phrase I don't know, leading to the written representation I dunno.
The resulting word form after apocope has occurred is called an apocopation.
