menestyksekkäimmin

Menestyksekkäimmin is the superessive case of the Finnish word "menestyksekäs," which means successful. The superessive case is a grammatical case used in Finnish to indicate location on top of something, or in a figurative sense, to mean "on" or "in addition to." Therefore, "menestyksekkäimmin" translates to "most successfully."

This adverbial form is used to describe an action or event that has been performed or has occurred in the most successful manner compared to other possible ways or instances. For example, one might say a project was completed "menestyksekkäimmin" if it surpassed all other projects in terms of achieving its goals, efficiency, or positive outcomes. It implies a superlative degree of success.

The formation of the superessive case in Finnish typically involves adding the suffix "-llä" or "-llä" to the genitive stem of the noun. However, for adverbs derived from adjectives like "menestyksekäs," the superlative form is often created by first forming the superlative of the adjective ("menestyksekkäin") and then adding the case ending. In this instance, "menestyksekäs" (successful) becomes "menestyksekkäin" (most successful), and then the superessive ending "-llä" is applied, resulting in "menestyksekkäimmin." It signifies the highest possible level of success.
