'terrain-optimized' originates from the combination of 'terrain' and 'optimized', where 'terrain' refers to the physical features of a tract of land and 'optimized' means made as effective as possible.

The term 'terrain' comes from the Latin word 'terra', meaning 'earth', and 'optimized' is derived from the Latin 'optimus', meaning 'best'.

Initially, 'terrain' referred to the physical features of land, and 'optimized' meant making something as effective as possible. The combined term 'terrain-optimized' has retained this meaning.
