な-adj/noun + ので [because structure]


Currently I am studying the ~ので,。。 grammar and, according to the book, I
should use the short form before it, such as in `もっと勉強したので、頭が痛いです。` Then, when
I have a な-adj or noun, can I write it as follows for the presente tense ??:
`元気だので、外に行きます。`instead of `元気なので、外に行きます。`which is the correct form according
to the text book? or is it wrong?




Not sure what you mean by the 'short form'. I'm guessing you mean the
dictionary form rather than masu form. So, as you say, 勉強したので is correct.

元気 **だ** ので is wrong. In the non-past tense nouns and na-adjectives both take
な; never だ. So you would have 元気 **な** ので, 先生 **な** ので etc.

However, in the past tense you would still use だった; there is no replacement
with な in this case. So 元気 **だった** ので, 先生 **だった** ので etc.
