Lõplikul
Lõplikul is the adessive singular form of the Estonian adjective lõplik, meaning final or definitive. In Estonian, adjectives agree with the nouns they modify in number and case, so lõplikul appears when the associated noun is in the adessive case. This form is used to indicate location or context rather than to alter the core meaning of the word.
Etymology and formation: The form is produced by adding the Estonian adessive suffix -l to the stem
Usage: Lõplikul is most often found in formal or written Estonian, including administrative, legal, and literary
Examples (illustrative, showing function rather than fixed expressions): lõplikul kohal (at the final place), lõplikul hetkel
