Etymology
The term 'arm's-length' is a metaphorical compound drawn from the physical act of holding something at a distance with one's arm fully extended. This literal gesture, implying a desire to avoid close contact or intimacy, was adopted into legal and commercial English in the early 20th century. It evolved to describe a formal, impartial relationship where parties maintain independence, as if physically separated. The logic is direct: the physical distance ensures no covert influence, perfectly translating into the abstract principle of objective, disinterested dealings in business and law.
Analysis
This is a compound adjective formed from the possessive form of the noun 'arm' and the noun 'length'. 'Arm' originates from Old English 'earm', of Germanic origin. 'Length' originates from Old English 'lengthu', from the Germanic root of 'long'.
