Morphology
past-tense + morpheme
The phrase is fully compositional: 'past-tense' specifies the temporal value and 'morpheme' denotes a minimal unit of meaning, so together they literally mean a morpheme that marks past time. This concept is morphologically and cross-linguistically common (many languages have a past-tense marker), so a B1 learner who knows the constituent words will readily understand the term.
Etymology
Past-tense morpheme means a small part of a word that shows an action happened before. Imagine adding -ed like a little stamp to a verb — talk becomes talked — and that stamp tells you the action is 'past' or 'already done'.
