Etymology
the word 'harmless' is a straightforward compound formed within old english, combining the noun 'harm' with the adjectival suffix '-less'. the root 'harm' itself has germanic origins, deriving from proto-germanic harmaz, which conveyed a sense of injury or grief. the suffix '-less' is a productive english morpheme from old english -lēas, meaning 'devoid of'. therefore, the literal construction 'devoid of harm' has remained semantically transparent, evolving from a concrete description of physical safety to also encompass abstract notions of being inoffensive or benign.
Analysis
harm (old english, noun meaning 'injury, damage, hurt'), less (old english, suffix forming adjectives meaning 'without, free from').
