'anglemeter' is formed from the English word 'angle' and the suffix '-meter', where 'angle' means 'the space between two intersecting lines' and '-meter' means 'measuring device'.

'anglemeter' was coined in modern English by combining 'angle' and '-meter', following the pattern of other measuring instruments like 'thermometer' and 'barometer'.

Initially, it meant 'a device for measuring angles', and this meaning has remained unchanged in modern usage.
