The kanji 縮 is a 形声文字 (keisei moji), a phono-semantic compound character. The left side, 糸 (いと), is the semantic component, indicating "thread" or "fiber," relating to cloth or fabric. The right side, 宿 (しゅく/やど), is the phonetic component, which provides the sound and hints at the meaning. 宿 originally meant "lodging" or "to stay." The combination suggests the concept of thread or fabric becoming compact or shortened, hence "to shrink."
