rakentettua

Rakentettua is a Finnish non-finite form derived from the verb rakentaa (to build) and is the partitive singular form of the passive past participle rakennettu, meaning built or constructed. It functions as a participial adjective that describes a substance or material that has undergone construction.

In Finnish grammar, the partitive case is used with mass nouns or when the quantity is indefinite. Therefore rakentettua typically appears with uncountable nouns such as materials or substances, indicating that the material has already been created or cast but is not being counted as a discrete whole in the sentence. The form contrasts with rakennettu (the nominative/attributive form) and with other cases like rakennetun in the genitive.

Common contexts for rakentettua include construction, architecture, and manufacturing, where one refers to materials or substances that have been prepared through a building process. It can describe the state of a material rather than a completed object, emphasizing the condition "that has been constructed" rather than the entirety of a thing.

Examples (Finnish usage):

- Rakentettua betonia käytetään tämän projektin lattian valamiseen.

- Rakentettua puuta käytetään usein sisäpinnoitteisiin.

- Rakentettua materiaalia kierrätetään rakennusjätteestä.

Related forms include rakennettu (past participle, nominative singular), rakennettujen (genitive plural), and rakennetut (nominative plural), with corresponding partitive forms like rakennettuja. See also Finnish grammar sections on the past passive participle, partitive case, and adjective use.
