 The Chukchi word "təmeyŋəlevtpəγtərkən", for example, meaning "I have a fierce headache", is composed of eight morphemes "t-ə-meyŋ-ə-levt-pəγt-ə-rkən" that may be glossed.The morphology of such languages allows for each consonant and vowel to be understood as morphemes, while the grammar of the language indicates the usage and understanding of each morpheme.The discipline that deals specifically with the sound changes occurring within morphemes is morphophonology.
