The kanji 症 is a 形声文字 (keisei moji), a phono-semantic compound character. It is made up of two parts: ⚫︎The radical, 疒 (やまいだれ - yamaidare), on the left, which signifies "sickness" or "disease." ⚫︎The phonetic component, 正 (shou), on the right, which gives a hint to the sound of the character. This component provides the sound and also contributes to the meaning, as 正 (sei/shou) can relate to "correctness" or "accurate indication," subtly suggesting the identification of symptoms related to disease or sickness.
