Etymology
The word 'instrumental' traces its lineage to the Latin verb instruere, meaning "to build, arrange, or equip." This verb combined the prefix in- (upon) with struere (to pile, build), a root also seen in 'structure'. The noun-forming suffix -mentum was added to create instrumentum, signifying "a tool, equipment, or means." Finally, the adjectival suffix -alis was appended, shifting the meaning from the tool itself to the quality of being like or serving as a tool. Thus, the literal sense of "relating to an instrument" evolved into the modern abstract meanings of being an essential means to an end or pertaining to musical instruments.
