真 — 匕 (spoon) over 目 (eye) over 八 (eight/base)
真 originally depicted a person or vessel used in ritual, conveying the idea of something genuine or true. Over time the form was reanalyzed as components like 匕, 目, and a base, but the core meaning of 'real, true, genuine' has remained stable since early bronze inscriptions.
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'.
