Meaning
At its core, 落 means to fall, drop, or descend. But one kanji rarely stays literal. A person falls from social status. A student fails an entrance exam. A city falls to an invading army. A negotiation finally settles. Physical, academic, social, military — all of these meanings trace back to this single character, which is why 落 is essential at the N2 level.
Break apart the structure: the top radical is 艹 (grass crown, 草冠), representing vegetation. Below it sits 洛, itself composed of 氵 (water radical) and 各. The original image is dew or water droplets falling from blades of grass — something descending naturally from a plant. Over centuries, the meaning widened from that literal drop to any downward movement, then to abstract concepts of decline and failure.
Japanese children learn 落 in Grade 3, around age 8 or 9. It has 12 strokes. At that age, the basics stick: leaves fall, objects drop. The subtler senses — social decline, exam failure, a negotiation reaching resolution — emerge later, which puts the full vocabulary squarely at N2.
Visually, picture the grass radical as leaves on a branch and the lower half as water in motion. Once you know the origin, the shape falls into place.
Readings
On'yomi (音読み) — Chinese-derived readings
The on'yomi is ラク (raku), from Middle Chinese. It appears mainly in kango — compound words of Chinese origin — and dominates formal, academic, and literary contexts.
- 落下 (rakka) — falling, descent; used in science and news reporting, e.g., falling debris or a dropped object
- 落第 (rakudai) — failing an exam or being held back a grade; carries real weight in Japan's exam-focused culture
- 落語 (rakugo) — traditional Japanese comic storytelling; literally "falling words," referring to the punch line that ends each performance
- 転落 (tenraku) — a sudden tumble in status or fortune; can be physical or metaphorical
- 墜落 (tsuiraku) — crash, plunge; the standard word for aircraft crashes
- 没落 (botsuraku) — ruin, the downfall of a person, family, or empire
One phonological note: when ラク precedes a hard consonant, the ク contracts to っ. So ラク＋カ → らっか (not らくか). You'll see this in both 落下 and 落花 — same pronunciation, different kanji. This consonant doubling is standard across many ラク compounds.
Kun'yomi (訓読み) — Native Japanese readings
The kun'yomi readings are お.ちる (ochiru) and お.とす (otosu). Both are native Japanese verbs. The dot marks where the okurigana — the hiragana endings — begin.
おちる (ochiru) is intransitive: the subject falls on its own, with no agent causing it.
- 葉が落ちる (ha ga ochiru) — the leaves fall
- 成績が落ちる (seiseki ga ochiru) — grades decline
- 落ち着く (ochitsuku) — to calm down, to feel settled; one of the most useful expressions in the whole family
おとす (otosu) is the transitive counterpart — you drop something, or cause something to fall.
- 財布を落とす (saifu wo otosu) — to drop one's wallet
- 試験に落とす (shiken ni otosu) — to fail someone in an exam (you are the examiner here, not the test-taker)
- 声を落とす (koe wo otosu) — to lower one's voice

Memory Tip
Picture a Japanese garden in autumn: blades of grass (the 艹 radical on top) are wet with morning dew, and sparkling water droplets (the 氵 component below) slide slowly off each blade and fall to the ground. That's the image frozen inside 落 — dew falling from grass.
From that one scene, the meanings branch out. Things fall. People fall from grace. Students fall short on exams. Voices fall to a whisper. The grass is always releasing something downward.
