läähtien

Lähtien is a Finnish adverbial form derived from the verb lähteä, meaning to depart or to start. In contemporary Finnish, lähen is used to indicate the starting point of a time period, a price level, or a regulatory scope, roughly equating to the English “from” or “starting from.” The form is most common in written or formal language and is less frequent in everyday speech, where alternative expressions such as alkaen or alkaen are often preferred.

Typical usages include time references, such as vuotena 2010 lähtien meaning “since 2010” or from 2010 onward. It can also appear with prices or quantities, as in liput 15 euroia lähtien meaning “tickets from 15 euros.” Additionally, läähtien may be used to specify the scope of rules, programs, or services starting at a certain point in time or at a given amount.

Etymologically, lähen borrows its meaning from the noun lähtö (departure) or the verb lähteä (to depart/start), with the -ien suffix forming an adverbial participle that attaches to the following clause to anchor it to a starting point.

In summary, lähti­en is a formal Finnish device for anchoring statements to a starting reference point—time, price, or scope—while everyday language often favors alkaen for similar ideas.
