measure density

Etymology
Etymology Information

'densitometer' originates from modern English formation combining 'density' (from Latin 'densitas') and the Greek-derived suffix '-meter' (from 'metron'), where 'density' referred to compactness and 'metron' meant 'measure'.

Historical Evolution

'density' came into English via Latin 'densitas' (from 'densus' meaning 'thick, compact'), while the element '-meter' derives from Greek 'metron' ('measure') through New Latin/modern scientific coinage; these parts combined in modern English to form 'densitometer'.

Meaning Changes

Initially coined to mean 'an instrument for measuring density' in scientific/technical contexts, and it has retained that specialized meaning.
