一度いちども〜ない

Similar

• 誰だれも〜ない

  Same も＋negative frame, a different axis emptied — 誰だれも counts PEOPLE down to none, 一度いちども counts OCCASIONS down to none, so あれから一度いちども乗のらない empties a count of times rather than a set of people.

• 何なにも〜ない

  Same frame, and 一度いちども denies a NUMBER of occasions rather than an OBJECT — 何なにも食たべない reports nothing eaten on this one occasion, 一度いちども食たべたことがない reports the occasion has never once happened at all.

• どこにも〜ない

  Same も＋negative frame over a different axis — どこにも empties a set of PLACES, 一度いちども empties a COUNT of times, and only 一度いちど needs its own counter word (度ど) where どこ stands bare.

• 決けっして〜ない

  決けっして denies the occasion on principle, as a refusal or a pledge holding for all future time (決けっして言いわない promises silence going forward); 一度いちども denies it as a plain count of how many times it has happened so far (一度いちども言いったことがない reports zero occasions in the past), so only 決けっして sits naturally in a vow.

Lookalikes

• もう一度いちど

  Same 一度いちど, opposite word in front of it — もう一度いちど asks for one more instance of something that already happened at least once, while 一度いちども denies there was ever a first instance at all.

never, in the sense of not once — 一度いちど plus も under a negative predicate empties a count of occasions to zero

have never done — with たことがある for experience, denying that the experience has ever happened
