| suppletion |
| Definition: The phenomenon where a term in a grammatical paradigm has no resemblance to the base form. |
| Example:
The went in the paradigm go/goes/going/went/gone. Note: the oddball went is called a suppletive form. |
| Etymology: The word derives from the Latin supplētus, the past participle of supplēre, to supply. |
| Oxford English Dictionary: The word's first citation is from 1933: "Athematic verbs, as well as their semantic equivalents elsewhere, seem peculiarly liable to suppletion by other verbs to furnish their aorists." (L. H. Gray in Language IX. 84) |
