Korkeiksi

Korkeiksi is a Finnish grammatical form: the translative plural of the adjective korkea, meaning high or tall. In Finnish, the translative case (‑ksi) expresses a change of state or designation, so korkeiksi is used when multiple subjects are described as becoming or being regarded as high or tall.

The form is most often found with verbs that express becoming or transformation, such as muuttua (to become) or tulla (to come to be). In sentences, korkeiksi accompanies a plural subject and signals that the subject has taken on the quality of being high or tall. It can refer to physical height, but it can also be used figuratively to describe status or importance when expressed as a transformation.

Typical usage and nuance:

- It denotes a change into the state of being high or tall, rather than a simple present attribute.

- It tends to appear in descriptive or formal writing, including landscape or architectural descriptions, where height is a relevant property.

- It often contrasts with singular forms like korkeaksi (to become tall/high for one thing) or korkeina (when describing a plural attribute in other grammatical cases).

Examples:

- Puut muuttuvat korkeiksi kevään myötä. (The trees become tall as spring progresses.)

- Rakennukset on suunniteltu soiksi korkeiksi ilmeen vuoksi. Note: this second example demonstrates the general idea; more natural phrasing would be chosen in actual text.

In summary, korkeiksi is the plural translative form used to express that multiple subjects have become or are designated as high or tall, typically in descriptive or formal contexts.
