球迷
qiú mí · HSK 3
fan (ball sports)
⚽ 球 (ball) + 迷 (fan/obsessed) = ball-obsessed = sports fan
球 means ball; 迷 means to be enchanted or a devotee (same 迷 as in 影迷 movie fan, 歌迷 music fan). So 球迷 literally decomposes to ball-devotee — someone hooked on ball sports.
球 — jade radical 玉/王 + qiu 求 (phonetic)
球 is a semantic-phonetic compound. The left side 王 is the 'jade' radical, indicating the original meaning: a fine piece of jade or a jade ornament. The right side 求 supplies the sound 'qiu'. Over time the meaning broadened from a jade sphere to any round object, and today it most commonly means 'ball' or 'globe'.
迷 — 辶 (walk) + 米 (rice/mǐ, phonetic)
A semantic-phonetic compound. The 辶 component (walking/road) gives the meaning of going astray on a path, while 米 (mǐ) supplies the sound. Originally referring to losing one's way while traveling, it later extended to mean confused, lost, or fascinated/captivated by something.
