What does suppletive mean?
Suppletive describes the phenomenon of grammatical suppletion, in which a word uses one form in place of the form that regular inflection would predict. It can also refer to the replacing form itself. English provides many familiar examples: the past tense of "go" is "went," and the past participles of "be" include "been" and "were," alongside forms such as "was" in the simple past. These irregularities are not errors or arbitrary exceptions; they are established features of the language's grammatical systems. The term is especially useful in historical linguistics, morphology, and the study of inflection. A suppletive form may replace another form within the same paradigm, so that grammatical functions such as tense or number are expressed through a stem from a different etymological source. In ordinary usage, the word is likely to appear in detailed discussions of English verbs or in comparisons among languages.

Where does suppletive come from?
The word comes through Latin from supplēre, meaning "to fill up" or "supply." The later Latin adjective suppletivus was associated with supplying or replacing, and English developed both the adjective and the noun meaning a grammatical form used in place of another. English cognates such as supplement, supplementary, and supplemental share the same Latin foundation.
