Task: Question Generation
Input (English): In Dutch, the diminutive is not merely restricted to nouns and exist in numerals (met z'n tweetjes, "the two of us"), pronouns (onderonsje, "tête-à-tête"), verbal particles (moetje, "shotgun marriage"), and even prepositions (toetje, "dessert"). Most notable however, are the diminutive forms of adjectives and adverbs. The former take an diminutive ending and thus functions as a noun, the latter remain adverbs and have always the diminutive with the -s appended, e.g. adjective: groen ("green") → noun: groentje ("rookie"); adverb: even ("just") → adverb: eventjes ("just a minute").
Output (English): When the diminutive ending "-tjes" is added to the adverb "even," as what part of speech does it function?
