ample

The word 'ample' entered English in the late 15th century from the Old French 'ample', which itself came from the Latin 'amplus', meaning 'large, spacious, extensive'. The Latin term is likely derived from the Proto-Indo-European root 'h₂em-', meaning 'to grasp', which also gives rise to words like 'amplexus' (an embrace) in Latin. The semantic journey moved from the physical concept of an encircling grasp to the more abstract idea of spaciousness and abundance. Over time, the English usage evolved to describe not only physical spaciousness but also sufficiency and generosity in quantity.

The word 'ample' is a simplex word borrowed whole from French. It does not contain separable morphemes in its modern English spelling.
