viihteellistäkin
viihteellistäkin is a Finnish word that functions as an adverb. It is the comparative form of the adverb "viihteellinen," meaning "entertaining" or "amusing." Therefore, "viihteellistäkin" translates to "even more entertaining," "more amusingly," or "somewhat more entertaining." The suffix "-kin" adds a sense of emphasis or a slight qualification, suggesting that something is not only entertaining but perhaps even more so than previously implied or compared.
The word is often used in contexts where a comparison is being made, either explicitly or implicitly.
