下す
おろす · orosu · JLPT N3 · verb-godan
to lower
⚓ 下 = down; orosu sounds like a rose, set down gently into a vase
The kanji 下 means below or down, the same character as in 下 (shita, underneath). Add the sound hook: oh-ROSE-u, a rose you lower down. Used for lowering things like an anchor, a flag, or luggage from a shelf.
下 — horizontal line 一 + mark below
下 is an indicative character: a long horizontal line represents a reference level, and a shorter stroke placed beneath it points to the area below. The original meaning 'below, down' comes directly from this spatial diagram, and it later extended to verbs like 'descend' and 'lower'.
