だんだん (だんだん) — Japanese Vocabulary

だんだん — だんだん (dandan)

Part of speech: adverb JLPT level: N4 Reading: だんだん (dandan) Meaning: gradually, little by little, step by step

Word Breakdown

だんだん is a gitaigo (onomatopoeic/mimetic word). It is written exclusively in hiragana. Etymologically, it originates from the kanji 段々 (meaning "steps" or "levels"). While you may occasionally see it written as 段々 in older texts or formal writing, it is standard practice in modern Japanese to write it in hiragana to emphasize its adverbial nature. The repetition of "dan" mimics the idea of climbing stairs or progressing through stages.

Common Mistakes

❌ だんだん + past tense only → ✓ だんだん + change-of-state verbs — Dandan describes a process. It is most naturally used with verbs that indicate change, such as naru (to become), kuru (to come/progress), or iku (to go/proceed).

❌ だんだん + static state → ✓ だんだん + dynamic process — You cannot say "It is gradually red" (a static state). You must say "It is gradually becoming red" (だんだん赤くなる).

In Context — Mini Dialogue

B: まだ難しいけど、だんだん分かってきたよ。(Mada muzukashii kedo, dandan wakatte kita yo.) — It’s still difficult, but I’ve gradually started to understand it. A: それは良かった！ (Sore wa yokatta!) — That’s great! B: うん、毎日勉強しているからね。(Un, mainichi benkyou shite iru kara ne.) — Yeah, because I’m studying every day.

Usage Notes

Nuance: Dandan is a very common, neutral adverb. It is appropriate for both casual conversation and polite speech. It implies a process that happens over a period of time, rather than an instantaneous change.
Collocation: It is almost always paired with verbs of change. The most common pattern is [Adjective/Noun] + に + なる (e.g., samuku naru - to become cold) or [Verb] + てくる/ていく (e.g., wakatte kuru - to come to understand).
Comparison: While jojo ni (徐々に) carries a similar meaning, it sounds more formal or academic. Sukoshi zutsu (少しずつ) focuses more on the "small amount" aspect of the change, whereas dandan focuses on the "progression" or "steps" of the change. Use dandan for everyday, natural flow.
