'grass-associated' is a compound word formed by combining 'grass' and 'associated'. 'Grass' originates from Old English 'græs', meaning 'herb, plant, grass'. 'Associated' comes from Latin 'associatus', the past participle of 'associare', meaning 'to unite, ally'.

'Grass' has remained largely unchanged from its Old English form 'græs'. 'Associated' evolved from Latin 'associare' through Old French 'associer' to Middle English 'associate'.

The term 'grass-associated' has consistently referred to things related to or connected with grass.
