About だけでなく

だけでなく (an abbreviation of だけではなく) is a common construction in Japanese which translates to 'not only (A), but also (B)'. Sometimes the (B) statement may be left unsaid. This expression may connect to any (A) phrase that だけ would usually be able to connect to.

Caution

The で in では is not the particle で, but the auxiliary verb だ in its conjunctive form. は is regularly dropped from では expressions, or it may also be changed to じゃ, for ease of pronunciation.

The conjunction particle て should follow なく, as it is the conjunctive form of the い-Adjective ない. However, the て in this particular construction is very often omitted.

Caution

In writing, if there is no comma (known as a 読点(とうてん) in Japanese) after なく, the full なくて construction will be required. When a comma is present, both forms are grammatically correct.

Shouldn’t it be added that も is added behind the but also section?
It at least seems like that’s supposed to happen.

Hey,
I have added following information: " It is often used together with second noun + も (meaning “also”) in main clause…" and applied formatting to all ”も" used in examples.

Does it make it more clear?

Cheers!

Why is だけでなくて not accepted in this grammar point, but it is accepted in だけでなく(て)～も (https://bunpro.jp/grammar_points/481)?
Pushindawood
Excellent question! I have updated the grammar point to accept だけでなくて as an alternate answer. Cheers!

Is it also worth adding Tobira page 21 to the resources section?

Why is this wrong?

@Liras348
Realistically speaking, it’s not. However, Bunpro was looking for a formal/polite grammar and ばかり is the formal equivalent of だけ, which is why your answer was marked as wrong.

(see “caution” section of grammar point)
