The kanji 隻 is a phono-semantic compound (形声文字 - けいせいもじ). The left side is a part called "shibu" (偏 - へん), which indicates meaning, related to the left side part of 手（て）(hand) or 爪（つめ）(nail), suggesting taking hold of something. The right side is "seki" (石 - いし - stone), which represents the sound. Therefore, it originally depicted the act of holding something with one hand. The character was later borrowed to represent "one" or "single," particularly for counting things.
