Morphology
stemmed = stem (semi-transparent) = stem + ed
Derivationally regular (past participle of the technical verb 'to stem'), but the meaning is specialized to NLP and may not be obvious from the common noun.
Etymology
Stemmed in computing uses the idea of a stem as the base of a word, like the main part of a plant's stalk, and cuts words down to that base form. So when text is stemmed, a search can treat 'run', 'runs', and 'running' as the same idea.
