kaksinkertaiseksi

Kaksinkertaiseksi is the translative form of the Finnish adjective kaksinkertainen, meaning twofold or double. It expresses a change of state, indicating that something becomes two times as large or as much as a reference point. The form is typically used with verbs that denote becoming or increasing, such as kasvaa (to grow), tulla (to become), or muuttua (to change), and it can also follow the verb tehdä to indicate making something twofold.

Grammatically, kaksinkertaiseksi is the translative case of kaksinkertainen. The translative case expresses a transformation or result, and thus kaksinkertaiseksi answers the question “into what?” in expressions of change. It is common in formal or quantitative contexts, such as reports or analyses, where a change in amount, size, or proportion is described. In everyday language, people may prefer phrases like kaksi kertaa suurempi (“two times larger”), depending on style and precision.

Usage notes: kaksinkertaiseksi is most natural when describing a measurable change or transformation. It typically follows verbs of becoming or changing, for example: myynti kasvoi kaksinkertaiseksi viime vuodesta (sales grew to twice as high as last year), hinta muuttui kaksinkertaiseksi (the price changed to be twofold). The term conveys exact multiplicative increase and is distinct from ironic or approximate expressions such as “kaksi kertaa suurempi,” which may be used in more casual speech.
