    Why does "kaeru" become "kaeranakucha", instead of "kaerinakucha"?

    Thank you so much for sharing these lessons, they are really helpful~ ♥

    I've been reading this lesson of yours over and over again but I have something I still can't understand. I really hope you can give me a hint of what it actually means:

    仕事持ち帰らなきゃ行けないくらい忙しいなら
    (Shigoto mochikaeranakya ikenai kurai isogashiinara)

    I'm afraid I'm understanding the sentence in the wrong way, because I can only understand one single part; 仕事持ち帰らなきゃ
    But after that I don't know how to correctly read the sentence. The part which I can't fully understand is this one; 行けないくらい

    After several times of reading your lessons, i think the meaning is;
    If you are busy to the extent that you can't go without taking work home with you ...

    But still I'm not even sure if I can translate it like that.
    I really hope you can understandme and thanks you again~

    kaeru - plain form
    kaeranai - negative form
    kaeranakute - negative -te form
    So the proper sentence would look like this:
    kaeranakute wa dame
    And with the abbreviation (change nakute wa dame -> nakucha):
    kaeranakucha
