The kanji 疎 is a 形声文字 けいせいもじ (phonetic-semantic compound), combining a phonetic component and a semantic component. The left side is a radical 米 (rice), which provides a general association with agricultural settings and implies the idea of sowing or planting. The right side is 戶 (a door), which can represent an opening or distance. The combination suggests the idea of spreading out something sparsely or being separated. The historical development likely involved the association of rice seeds being scattered, with the meaning of the kanji extending to encompass the broader concepts of sparsity, separation, and distance.
