pitkä

Pitkä is a Finnish adjective meaning long or tall. It describes the extent of something or the duration of a period. Examples include pitkä tie (a long road) and pitkä päivä (a long day).

Finnish adjectives agree with the nouns they modify in number and case. The base form is pitkä; in plural nominative it becomes pitkät. In the genitive singular it is pitkän, and in the partitive plural it is pitkiä. The comparative form is pidempi and the superlative is pisin, as in pidempi tie (a longer road) and pisin tie (the longest road).

Pitkä is a native Finnish word, with cognates in related Finnic languages, such as Estonian pikk. It also appears in compound words and derivatives, for example pitkäaikainen (long-standing) and pitkäaikaisuus (longevity).

In onomastics, the element pitkä occurs in some Finnish surnames formed with the -nen suffix, such as Pitkänen, which reflects the historical use of adjectives in surname formation.
