Synonym discussion
Sense: abbreviation/1
'dist' is not a synonym of 'mi' (mile) or 'km' (kilometer) — it is the abbreviation for distance itself, while mi and km are units. A road sign might read 'Dist: 5 mi' or 'Dist: 8 km', using dist for the concept and mi or km for the unit of measurement. 'Light-year' is a unit for extremely large distances in astronomy and is never abbreviated. Use 'dist' only in written notations, labels, or tables; in ordinary text, write the full word 'distance' (e.g., 'The distance between Tokyo and Osaka is about 500 km').
Etymology
'dist' is a shortened (abbreviated) form of two separate English words: 'distance' and 'district'. 'Distance' came into English from Old French 'distance', which came from Latin 'distantia', meaning 'a standing apart' (from 'distare' — 'to stand apart'). 'District' entered English in the 1600s from French 'district', from Latin 'districtus' meaning 'territory under separate control'. The abbreviation 'dist' for both words became common in the 19th century with the growth of postal systems, railways, and map-making.
