I got confused by these forms. The book says that -くて(pos) and -なくて(neg) have to be connected with stem of an adjective, e.g. 安い: 安 + くて = 安くて.
The positive form is pretty easy to understand and master, but the negative one is a trouble for me. Basically, I got confused by an adjective 「汚い」. Its positive form would be 「汚くて」. But would the negative be 「汚なくて」? The reasons I got confused are that IME did not recognize the negative form, and those multiple 「な」 sound a bit odd to me.
Even google barely helped me with any of the i-adjectives in -なくて form except for 「おいしい」that was found accidentally here.
So, I wonder if I can add -なくて to ANY of the i-adjectives and be good with it.
And the last question. Is it actually -なくて form, or is it -くなくて?
