tätäkin

"tätäkin" is a Finnish word that functions as an adverb. It is a form of the demonstrative pronoun "tämä" (this) combined with the enclitic particle "-kin" (also, too). Therefore, "tätäkin" literally translates to "this also" or "this too".

Its usage is often to emphasize that something in addition to something else is also present or noteworthy. For example, one might say "Annoin hänelle tämän kirjan, ja tätäkin hän luki mielellään" which translates to "I gave him this book, and he gladly read this too". In this context, "tätäkin" refers to the book, implying that he also read other things or that this particular book was an additional item he enjoyed.

The word is used to broaden the scope of discussion or an observation, indicating that the current subject is not the sole item of interest but one among others. It can be used to express a sense of inclusivity or to add a further point to a previous statement. The grammatical case of "tätä" is the partitive, which is commonly used with demonstrative pronouns when they are the object of a verb or when referring to a part of something. The "-kin" particle attaches to the end of the word, signifying the addition of "also" or "too".
