The Grain Stalk Radical (禾 — Nogihen): Why 私 (I / Me), 利 (Profit / 便利), 秋 (Autumn) & 科 (Science) Share the Same Left Radical
Look closely at the left side of 私 (I / Me), 利 (Profit / 便利 Convenient), 秋 (Autumn), and 科 (Science): that is NOT a plain Tree (木)! Notice the slanted top stroke drooping down like a heavy ear of golden rice grain: 禾 (nogihen)!
What is the visual difference between the Tree radical (木 — kihen) and the Grain Stalk radical (禾 — nogihen)? A Tree (木) has a flat top with nothing above the horizontal branch. A Grain Stalk (禾) has a slanted top stroke drooping over the top like an ear of ripe rice or wheat bending under its own weight!
