JLPT0 G13 S0 F5000
䜌# is 絲 thread(s) + 言 (make verbal distinctions → distinct) → make tangled threads distinct by stretching and untangling them. 戀 adds 心 heart/emotions → attempt to untangle confused feelings (of longing, anxiety, or love) by figuratively stretching them straight (compare 攣 and 亂) → *long for*; *be anxious for*; *love*. The top element of the present form of the character represents a tremendous simplification.
