Katetuiksi

Katetuiksi is a Finnish grammatical form used to express a change of state into the condition described by the past participle katettu, meaning “covered.” It is a translative plural form, corresponding to the English “into becoming covered” or “to become covered.” It is used when describing something that becomes covered or overlaid as a result of an action or process.

Form and usage: Katetuiksi is the translative plural of the past participle katettu. The stem is katetu-, and the suffix -ksi marks the translative case, with the plural ending -iksi. It commonly occurs with verbs of becoming, such as tulla or muuttua: pinnat tulivat katetuiksi suojakalvon asennuttua. In this construction, the sentence expresses a change of state to a covered condition.

Examples and notes: The form is mainly found in formal or literary Finnish and describes processes or outcomes where surfaces or objects become covered. It is not a passive participle by itself, but a participial form used with a verb of becoming to indicate the new state.

In mathematics: The term katetuiksi is not standard in Finnish mathematical terminology. The legs of a right triangle are called kateetti (plural kateetit). If one intends to express “as a cathetus” in the translative, the appropriate form is kateeteiksi, not katetuiksi. For example, one would refer to the two sides of a right triangle as the kateetit, and in a descriptive sentence one might discuss their lengths or how they relate to the hypotenuse, while using kateeteiksi to indicate a state or role in a transformation if needed.
