Paksuisiksi

Paksuisiksi is a Finnish grammatical form derived from the adjective paksu, meaning thick or dense. It is the translative plural form, used to express a change of state into a thicker or denser condition when the subject is plural.

Morphologically, paksuiseksi would be the singular translative (to become thick), while paksuiksi is the plural counterpart. The form is built from the stem paksu- with the translative suffix -ksi, adjusted for number to yield -iksi in the plural. This form agrees with a plural subject and is used in clauses describing transformation.

Usage of paksuiksi typically involves verbs of becoming, such as tulla or muuttua. It describes a result-state rather than a qualitative description. For example, a sentence like Nesteet muuttuivat paksuiksi illustrates liquids that thickened after processing, with the subject in plural and the predicate in the translative plural.

In everyday Finnish, paksuiksi is more common in formal or descriptive language and in scientific or technical contexts. It contrasts with the singular paksuksi, which refers to a single thing becoming thick. Understanding the plural form helps in accurate agreement when the subject is plural.
