| Definition -
The language element to which affixes are attached. For example, the base of bobbing, bobs, and bobbed is bob.
1. The base is the part of the word that is listed in the dictionary.
Etymology - The term derives via Old French from the Late Latin bassus, thick, stumpy, or low. It is possibly related to the Greek basson, the comparative of bathys, deep.
Oxford English Dictionary - Its first citation in this sense is from 1845:
"The p is indicatory, signifying that, for the radical vowel of the base, a Guna letter or diphthong is to be substituted."
