fallen

The word 'fallen' originates from the Old English verb 'feallan', meaning "to drop from a height, fail, decay, die." This Old English term is derived from the Proto-Germanic 'fallaną', which carries a similar sense of falling. The Proto-Germanic root is traced further back to the Proto-Indo-European 'ph₂el-', meaning "to shake, swing, cause to fall," a root that also gives rise to words like Latin fallere (to deceive, trip up). The journey from a concrete physical action ("to drop") to abstract states ("having lost status," "morally degraded") is a classic example of semantic broadening, where the physical metaphor is applied to social, spiritual, and metaphorical declines.

The word 'fallen' is the past participle form of the verb 'fall'. It is not productively segmented into separate morphemes in its current adjectival usage. The root is the verb 'fall'.
