hehtaarin

Hehtaarin is the Finnish genitive singular form of the noun hehtaari, which denotes the hectare, a metric unit of area equal to 10,000 square metres (abbreviated ha). As a grammatical form, hehtaarin is used to show possession, measure and qualification in compound expressions.

In usage, hehtaarin appears in phrases such as hehtaarin hinta (price per hectare), hehtaarin verran (about a hectare, indicating an amount) and other constructions where the genitive links the unit to a noun or attribute. It also functions in attributive compounds and bureaucratic or agricultural contexts to describe land area, yields and land-use statistics.

The word hehtaari is a borrowing into Finnish corresponding to the international term hectare; the element hectare derives from French (hectare), formed from hecto- (hundred) and are (a unit equal to 100 square metres). In Finnish orthography the genitive singular ends with -n, producing hehtaarin. Pronunciation is approximately "HEHT-ah-rin".

Hehtaarin is common in everyday language relating to farming, real estate and environmental statistics, and appears in official documents, maps and data where land area is discussed. The standard abbreviation for the unit remains ha, while hehtaarin retains its grammatical role when the phrase requires the genitive.
