直zhí

--- Modern simplified form (簡體). 直 (zhí, “straight”) is unchanged from its traditional form, a pictograph that originally depicted a vertical line with horizontal strokes at top and bottom, symbolizing perfect straightness. It acts as a radical in 植 (plant), 殖 (multiply), 值 (value), and 置 (place), and its meaning of directness underlies many common words like 直接 (direct) and 直线 (straight line).
