Etymology
The compound adjective 'grass-fed' is a modern formation from two deeply rooted Germanic elements. 'Grass' originates from Proto-Germanic 'grasan', related to the act of growing and grazing. 'Fed' derives from the Proto-Germanic 'fōdijan', a causative verb related to 'fōdō' (food). The term emerged in the late 19th/early 20th century within agricultural discourse to specify a rearing method, creating a direct, transparent descriptor that contrasts with industrial 'grain-fed' practices. Its logic is purely denotative: it literally describes livestock that has been nourished primarily with grass, a meaning that remains entirely aligned with its constituent parts.
Analysis
Structure: grass (plant) + fed (nourished)
grass: From Old English 'græs', 'gærs', meaning 'herb, plant, grass'. In this compound, it denotes the primary source of nourishment.
fed: Past participle of the verb 'feed', from Old English 'fēdan', meaning 'to nourish, give food to'. In this compound, it functions as a participial adjective indicating how the subject was nourished.
