injury-free

the compound adjective 'injury-free' is a modern formation built from two distinct linguistic strands. the first element, 'injury', traces back to latin 'iniuria', meaning 'injustice' or 'a wrong', which itself combines the negative prefix 'in-' and 'ius' (law, right). its meaning narrowed in english to specifically denote physical harm or damage. the second element, 'free', originates from the old english 'frēo', related to the proto-germanic concept of freedom and exemption. when combined as a suffix in modern english, 'free' indicates the absence of the noun it follows. thus, 'injury-free' logically constructs the meaning 'exempt from harm', a concept essential in contexts like sports, workplace safety, and health reporting, where the absence of negative outcomes is the desired state.

Structure: injury (harm) + free (without) injury (from latin iniuria 'injustice, wrong', via anglo-norman injurie; functions as the noun base denoting harm). free (from old english frēo 'exempt from, not in bondage'; functions as an adjective-forming suffix meaning 'without' or 'lacking').
