Samanpituisia

Samanpituisia is a Finnish adjective form meaning “of the same length.” It is used to describe multiple objects that share an equal length.

The form is the plural partitive of the adjective samanpituisinen, which is built from sama meaning “the same” and pituus or its stem related to length. In Finnish grammar, adjectives inflect for number and case, and samanpituisia marks a plural partitive complement, often seen when the described quantity is indefinite or the predicate requires a partitive form.

Common contexts for samanpituisia include mathematics, design, architecture, and everyday comparisons of length. It frequently appears with numerals or plural nouns, especially in sentences describing several items with identical length.

Examples:

- Kolme viivaa ovat samanpituisia. (Three lines are of the same length.)

- Neliön sivut ovat samanpituisia. (The sides of the square are of the same length.)

Notes:

- A closely related form is samanpituiset, the nominative plural, used in different syntactic contexts.

- Samanpituisia is a typical illustration of how Finnish combines a basic meaning “the same” with a noun-related stem to express a specific comparative property.
