Not really… if you wanna learn something like swedish where you basically replace a few words in an english sentence and switch the word order to V2 it probably works but when you have languages like russian(because other slavic langauges warent even available last time i checked) or hungarian you enter a completely different level. Idk that much about russian but i can say for sure in hungarian you have to keep like 20 tables in mind constantly and have to be thinking about what roles the words in your sentence fill so you can attach the right suffixes and also keep in mind all the suffixes and vowel harmony for tense, aspect and mood, etc. Not to talk about word order, intonation and other affix related shenanigans.
