Hi there, I'm learning different forms of the adjectives now, one of them is the ~て form. The explanation was, when you use adjectives to connect two sentences or when you enumerate adjectives, you should use the ~て form. e.g.: たなかさんは せがたかくて、とても かっこいい ひと です (Mr. Tanaka is a tall, very handsome person) すしを たべなくて、 ぎゅうどんも たべない。 (I don't eat sushi; I don't eat gyuudon either. - I made that up, hope it works like that ) And then I came across dake dewa naku ...~mo, particularly this example: さちこは あたまが よかった だけ では なく、とても しんせつ でした (Sachiko was not only smart but also kind) Question: aren't "nai" forms of the verbs also handled as i-adjectives? Shouldn't it be だけ では なくて?
