ねぇ、ちょっと寄ってかない？ I came across this banner in a chat room. Would か need to be
added if its a question? I understand the phrase.

question
grammar words
Is the phrase ねぇ、ちょっと寄ってかない？ written incorrectly?
In casual speech, the か is can be omitted. If you raise the pitch on the last
syllable (like you would in English) the phrase is understood to be a
question. In casual writing (like texting, or in this case a chat room), you
can't add pitch, so punctuation serves to mark it as a question.

> 寄ってこない{LLLLHH}？ (Red bar indicates pitch, not emphasis)

> この本を読んだことある｛LLLLLHH｝？

This か is **normally** omitted.

As you know, か after a polite marker (です/ます) is very common (～ですか? / ～ますか? /
～ませんか?). However, in casual speech, か is rarely used, and people use rising
intonation instead.

  * 食べる？(↗) Wanna eat?
  * 食べない？(↗) Don't wanna eat? / Why don't we eat?

Actually, adding か here makes the sentence sound fairly **masculine and
blunt**.

  * 食べるか？ (masculine and blunt)
  * 食べないか？ (masculine and blunt)

For example, you may see this form used by a stereotyped stubborn father in
fiction. In reality, I would say speakers of standard Japanese almost never
speak like this. (Um, maybe male pet owners may speak like this to their cats
or dogs...)

Presumably this "ねぇ、ちょっと寄ってかない？" is said by a woman (this phrase is known as a
[Japanese _hosutesu_](https://en.wikipedia.org/wiki/Host_and_hostess_clubs)'s
classic way of touting), so there should **not** be か at the end.
