säänkestäviksi

Säänkestäviksi is the translative plural form of the Finnish adjective säänkestävä, meaning weather-resistant or weatherproof. The form expresses a change of state into weather resistance and is used to describe multiple items that have been made or designated to withstand weather conditions. The singular translative form is säänkestäväksi, while säänkestäviksi marks a plural subject.

In usage, säänkestäviksi typically appears with verbs that express making or becoming, such as tehdä, muuttaa, or käsitellä. It is common in technical, construction, and product-descriptions language to indicate that materials, components, or products have been treated or designed to be weatherproof. For example, Rakennuksen ulko-osat muutettiin säänkestäviksi means “The exterior parts of the building were made weatherproof,” and Kalusteet on suunniteltu säänkestäviksi means “The furniture is designed to be weatherproof.”

Etymology reflects its compound nature: sään- from sää (weather) and kestävä (durable). The suffix -ksi marks the translative case, while the plural form ends in -viksi to agree with a plural subject.

Notes: While säänkestävä describes weather resistance in general, säänkestäviksi is specifically used when stating that several items have become or been made weatherproof. It is less common in everyday speech than the base adjective, but frequent in manuals, specifications, and product labeling.
