passed

The verb 'pass' entered English around 1200 from Old French 'passer', meaning "to step, walk, or cross." The Old French term likely derived from Vulgar Latin 'passare', a verb created from the Latin noun 'passus', meaning "a step, pace." This Latin noun originates from the past participle 'passus' of the verb 'pandere', meaning "to stretch, spread out," referring to the extension of the leg in taking a step. The addition of the '-ed' suffix to form 'passed' follows the standard Germanic pattern for creating past tense verbs in English, a grammatical convention that became fixed in Middle English. Thus, 'passed' carries the combined legacy of a Latin root concerning physical movement and a Germanic grammatical structure indicating completed action.

The word 'passed' is the inflected form of the verb 'pass'. It is not productively segmentable into distinct morphemes in its current English spelling, as the '-ed' suffix is a standard inflection for the past tense and past participle.
