ametlikum
Ametlikum is an Estonian adjective meaning "more official." It is the comparative form of the adjective "ametlik," which translates to "official." The suffix "-um" in Estonian is used to form comparative adjectives, indicating a greater degree of the quality described by the adjective. Therefore, "ametlikum" implies a higher level of formality, authority, or adherence to rules and regulations when compared to something that is simply "ametlik."
For example, one might describe a document as "ametlik" (official) and another as "ametlikum" (more official).
