Taatakseen
Taatakseen is a Finnish verbal form formed from the verb taata (to guarantee, ensure) and the purposive suffix -akseen (modern orthography -akseen/-äkseen). Grammatically it is the third infinitive in a purposive construction, used to express purpose or intention with reference to a third person or an impersonal subject. Its basic nuance is "in order that he/she/it may ensure" or more tersely "to ensure" when the actor is not the speaker.
The form is common in formal and written Finnish and often appears in subordinate clauses of purpose.
Usage notes: taatakseen follows vowel harmony rules of the suffix, and the construction does not inflect for
