keskisuureksi

Keskisuureksi is the translative form of the Finnish adjective keskisuuri, used to express a change of state into the category of medium-sized. The translative suffix -ksi marks becoming or turning into something, so keskisuureksi literally means “into medium-sized” or “becoming medium-sized.” The form is created from the stem keskisuure- by adding the suffix -ksi.

Usage and examples:

- Yritys kasvoi keskisuureksi yritykseksi. (The company grew into a medium-sized company.)

- Kaupunki kasvoi keskisuureksi kaupungiksi. (The city grew into a medium-sized city.)

Keskisuureksi is typically used with verbs that denote transformation, such as tulla (to become), kasvaa (to grow), or muuttua (to change). In everyday language, speakers often use more common expressions such as keskikokoiseksi or keskikokoinen to describe medium size, but keskisuureksi remains correct and is found in formal, descriptive, or technical texts, especially when referring to predefined size categories or classifications. The form highlights a defined target state rather than a general attribute, and it is part of Finnish grammar’s translative case system.
