あまり〜ない / 全然〜ない: Degree Negation

あまり and 全然 are not ordinary degree words you can sprinkle into any sentence. They are bound to a negative: say あまり or 全然 near the start of a clause and you have opened a bracket that a sentence-final 〜ない must close. This page is about that structure — the negative-polarity dependency, and, crucially, what predicate the ない attaches to — rather than the fine shades of degree (how "not very" differs from "not much"), which live on the あまり / ちょっと page and the frequency page. Here the point is simpler and more mechanical: these adverbs commit you to a negative ending, and forgetting it leaves the thought grammatically stranded.

The bound frame: [adverb] … [〜ない]

Think of あまり and 全然 as the front half of a two-part frame. They announce a degree of negation and then reach forward to the predicate to supply the actual "not." Neither can stand alone.

This is the "negative-polarity" behaviour English speakers know from at all and any: fine in "I don't have any," broken in "×I have any." あまり and 全然 work the same way — they only appear where a negation is coming. So the moment your ear catches あまり or 全然, it should already be bracing for a 〜ない at the end.

What the 〜ない actually lands on

The structural payoff most textbooks skip: the closing negative isn't always a verb's 〜ない. It's whatever negative form the predicate takes. The adverb doesn't care about the word class — it just needs the predicate to end up negative. That means you have to know how to negate each type:

• Verb → 〜ない: あまり食べない
• い-adjective → 〜くない: あまり辛くない
• な-adjective / noun + copula → 〜じゃない / 〜ではない: あまり好きじゃない
• Existence ある → the irregular ない: お金があまりない

That last case is the sneaky one. あまり often modifies plain existence: お金があまりない = "there isn't much money." Because ある negates to the irregular ない (not ×あらない), the whole thing reads あまりない — a fused chunk you'll hear constantly (時間があまりない, 意味があまりない).

The same range applies to 全然, cranked to maximum:

The bracket can stretch a long way

The adverb and its ない don't have to be neighbours. The bracket can span an object, a time phrase, a whole chain of information — the negative just has to eventually arrive. Keeping the two halves connected across distance is the real skill, because that's where learners lose the thread and let the sentence end positive.

Here 全然 is separated from ていない by five words, and あまり from しない by a whole conditional clause — but the frame still holds, and a native listener has been waiting for that ない the entire time.

The one register exception (全然 + positive)

You will hear 全然 in front of a positive word — 全然大丈夫, 全然いい, 全然平気 ("totally fine"). This is genuine casual usage, not a mistake, but it is informal only and does not change the rule for the standard negative frame.

The full story of why this positive use exists, and when it's safe, is on the frequency page — the short version: use it with friends, never in formal writing, and when in doubt keep 全然 tied to a negative, which is correct in every register.

A family, not a pair

あまり and 全然 are the entry point to a whole class of negative-polarity adverbs. The same "adverb demands a ない" structure powers なかなか ("not readily"), 別に ("not particularly"), and めったに ("rarely") — each adding its own attitude to the negation — on the なかなか / 別に / めったに page, and it underlies 〜しか…ない ("only") too, treated on the 〜しかない page. Once you internalise "some adverbs come pre-committed to a negative," this entire corner of the grammar stops surprising you.

Common mistakes

Mistake 1 — Leaving the predicate positive. The adverb sets up a negation; without the ない the frame is only half-built.

Mistake 2 — Meaning "not at all" but forgetting the ない. English "at all" hides its negative inside itself; Japanese makes you spell it out on the predicate.

Mistake 3 — Regularising ある to ×あらない. あまり often modifies existence, and ある's negative is the irregular ない — never ×あらない.

Mistake 4 — Losing the negative across distance. In a longer sentence, learners open with 全然/あまり and then, by the time they reach the end, forget to negate.

Key takeaways

• あまり ("not very") and 全然 ("not at all") are negative-polarity adverbs: they open a frame that a sentence-final 〜ない must close.
• The closing negative takes whatever form the predicate needs — 〜ない (verb), 〜くない (い-adj), 〜じゃない (noun/な-adj), or the irregular ない for existence あまり…ない.
• The two halves can be far apart; keep tracking the bracket to the end of the sentence.
• 全然 + positive (全然大丈夫) is real but casual only — see the frequency page.
• Same structure, more flavours: なかなか / 別に / めったに and 〜しかない.
