kaksinkertaistat

Kaksinkertaistat is a Finnish verb form representing the second-person singular present tense of the verb kaksinkertaistaa, which means to make something twice as large or to double it. The base kaksinkertaista- comes from kaksinkertainen (twofold) plus the causative suffix -istaa, giving a sense of causing a doubling.

Usage and meaning: The form is used when the subject is explicitly “you” and the predicate expresses that you cause something to become two times as much. Example: Sinä kaksinkertaistat tämän summan. The construction is transitive, requiring an object that is being made twice as large. In many contexts, doubling is described with other constructions (for example, tuotanto kaksinkertaistuu for “production doubles”) rather than using the second-person form.

Grammatical notes: Kaksinkertaistat is the present indicative, second-person singular form. The infinitive and the third-person singular present form are both kaksinkertaistaa, which can create ambiguity in sentences without explicit subject and context.

Usage considerations: The term is primarily found in written Finnish and formal or technical contexts, such as finance, statistics, or business planning, where the action of causing doubling is described directly by the subject. In everyday language, native speakers may prefer passive or intransitive expressions like kaksinkertaistua to convey the same idea without specifying the agent.
