Negative (te-form) + しまう


I'm translating a song and came across this line:

> > 感じなくなっちゃえばいい

At first I thought it was:

感じる in negative te-form + しまう in conditional ば form + いい

But I think there's something wrong or something I'm ignoring. If I rewrite
the sentence the way I think it is, it would be like:

> > 感じる ---> 感じなくて
>>

>> ~てしまえば ---> ~ ちゃえば

>>

>> いい

So my guess would be :

感じなくちやえばいい

Why is there a 'なっ' before 'ちやえば'?




As you noticed, if that were the 感じる in negative te-form, it would be 感じなくて as
opposed to 感じなくな. That's why in reality it's 感じる + なくなる in te-form. Note that
なくなる is the adverbial form of ない + なる.

> 感じる ---> 感じ
>
> なくなる ---> なくなって
>
> ~てしまえば ---> ~ ちゃえば
>
> いい
