Sense: noun/1
In land measurement, 'are', 'hectare', and 'square meter' are all metric units but differ vastly in scale. An 'are' (100 m²) sits between the everyday 'square meter' and the large 'hectare' (10,000 m²). Think of an 'are' as roughly the size of a two-bedroom apartment or a modest garden. A 'hectare' is 100 times larger — about the size of a sports field. Most English speakers use 'square meters' for small plots and 'hectares' for farms or large properties. The 'are' itself appears mainly in formal land records across Europe, parts of Asia, and in older legal documents. For example: 'The vineyard covers 40 ares' (a manageable family plot) vs. 'The farm is 40 hectares' (a large commercial operation) vs. 'The room is 20 square meters' (an interior space).
Etymology
The verb 'are' comes from Old English 'earun' or 'aron', the plural present indicative of 'bēon' ('to be'). It is related to Old Norse 'eru' (meaning 'are') and Gothic 'sind' (meaning 'are'), tracing back to Proto-Germanic roots. The noun 'are', however, has a completely different origin: it was borrowed from French 'are' in the early 19th century, which itself came from Latin 'area' meaning 'open space' or 'level ground'. The noun was adopted as a metric unit of area in France around 1795 and later spread to other countries using the metric system.
