The kanji 疎 is a 形声文字 (keisei moji), a phono-semantic compound. The left side is a radical called 疋 (hi, hiku) meaning "foot," "to walk," or "to stride," suggesting movement or distance. The right side is 侖 (ron), which contributes to the sound and perhaps originally implied “thread or strand," which could relate to the idea of "thin" or "sparse." So the combination suggests moving far, or that things are thin or separated in distance. Over time, the meaning evolved to encompass concepts like "distant" and "estranged."
