The Arrow Radical (矢): Why an Arrow Unlocks 知 (Know — Shiru), 族 (Family — Kazoku) & 医 (Doctor — Isha)
Look at the left side of 知 (Know), the bottom-right of 族 (Family), and the center of 医 (Doctor): all three hold 矢 (Arrow — ya)! Plus learn how to never confuse 矢 (Arrow) with 失 (Lose).
Be careful not to confuse the 矢 (Arrow) component inside 知, 族, 医 with 失 (Lose — ushinau)! In 矢 (Arrow), the top slanted tip stays cleanly ABOVE the horizontal bar like a feathered arrowhead. In 失 (Lose), the center line pokes all the way through the top!
Quick Comparison: 知 (Know) vs. 族 (Tribe) vs. 医 (Medicine) vs. 失 (Fault)
See how 矢 (Arrow) powers 知, 族, and 医 (and contrasts with 失) below:
| Kanji & Meaning | Primary Readings (Bold = Primary) | Shibashi Visual Mnemonic Hook | Common Compound Word |
|---|---|---|---|
| 知 — Know | On: ち Kun: し |
矢 (Arrow) on the left + 口 (Mouth) on the right = speaking words as fast and straight as an arrow = KNOW / WISDOM (shiru / chi). | 知る (しる) — to know |
| 族 — Tribe | On: ぞく Kun: — |
方+𠂉 (Clan banner flag) + 矢 (Arrows) = people united under one banner and quiver of arrows = FAMILY / TRIBE (zoku, as in 家族 kazoku). | 家族 (かぞく) — family |
| 医 — Medicine | On: い Kun: — |
匚 (Medical box) enclosing 矢 (Arrow/Needle) = extracting an arrow wound = DOCTOR / MEDICINE (i). | 医者 (いしゃ) — medical doctor |
| 失 — Fault | On: しつ Kun: うしな |
Center vertical sweep pokes UP THROUGH the top bar (unlike 矢 Arrow!) = LOSE / SLIP (ushinau / shitsu). | 失う (うしなう) — to lose, to part with |
