Hi there. First, as a personal suggestion, you should consider the version given from some available internet multilingual translator(s) only as an initial source of references. You need to somehow double check the accuracy by looking through the translated version very carefully. As given for your case, "Ich habe mich in y gesunken", I honestly say that it can never be Russian, because principally, the characters are not written in Cyrillic characters. Secondly, for "ich", "habe", "mich", and "gesunken", these are obviously some German words instead. Nevertheless, if we ignore the wrong translation "y" in the sentence, this actually means (in German) "I have fallen (or sunk) myself in...", but it does not provide you the necessary translation of the verb "to fall in love". Therefore, I believe that you might have wrong clicked some icons during the translation. So, as given from the other respondent, "to fall in love (with so.)" is generally translated as "влюби́ться (в кто́-то[вин])": www.wordreference.com/enru/fall%20in%20love (please look for the example, v.i. 4.: he fell in love with her) The verb "влюби́ться" is a reflexive verb given in perfective sense (instead of "влюбля́ться" in imperfective sense), possibly because it describes a one-time action, to fall in love. Hence, "to have fallen in love (past tense)" then becomes "влюби́лся" (for masculine subject), "влюби́лась" (for feminine subject), and "влюби́лись" (for plural subject). In addition, "тебя́" is the accusative or genitive case of the subject pronoun "ты" (informal you). On the other hand, in German, "to fall in love (with so.)" is generally translated as "sich[Akk] (in jdmn.) verlieben": dict.leo.org/ende?lp=ende& search=fall+in+love So, "I have fallen in love with you" would possibly be translated as: "Ich habe mich in Dich verliebt". Good day and ciao ciao.

I've fallen in love with you - Я влюбилась в тебя (female) Я влюбился в тебя (male) "ich habe mich in y gesunken" I think it's german :))

Я влюбилась в тебя.(female) Я влюбился в тебя.(male)
