One distinctive feature that has caused a great amount of interest among linguists is what is traditionally seen as three degrees of phonemic length: short, long, and "overlong", such that /sɑdɑ/, /sɑˑdɑ/ and /sɑːdɑ/ are distinct. In actuality, the distinction is not purely in the phonemic length, and the underlying phonological mechanism is still disputed.[citation needed]
