。
There's no end to it.
Literal
Limit [subject-が] exist-not.
An idiom meaning 'there's no limit/end' — used when something is endless, when a list goes on forever, or when there's no point trying because the task can't be finished. きり is written 切り or 限り in kanji but usually appears in kana in this expression. ない is the negative of ある (to exist).
