Poissulkeakseen

Poissulkeakseen is a Finnish verb form meaning “in order to exclude” or “to rule out.” It is the third infinitive of the verb poissulkea, formed with the suffix -akseen to express purpose. The form is used to introduce an infinitive clause that states the purpose of the action described by the main verb, and the subject of the infinitive generally corresponds to the subject of the main clause.

In usage, poissulkeakseen is common in formal or written Finnish, such as scientific, legal, or policy texts, where authors explain the aim of a procedure or procedure steps. The construction typically follows a finite verb and precedes a complement that states what is being excluded, e.g., additional tests were conducted poissulkeakseen epävarmuudet in the study. The English rendering is often “in order to exclude” or “to rule out,” though the exact nuance depends on context.

Etymology and form: poissulkea means “to exclude” or “to rule out,” and the suffix -akseen marks a purposive third infinitive. This form differs from the first infinitive (the base form) and other non-purposive infinitives in Finnish. The poissulkeakseen construction is more common in formal registers and may appear alongside other purposive infinitives to clarify aims or methods.
