left-falling stroke (here: marker of dropping motion)
Top falling stroke - abstract marker depicting something slipping or falling away from the body. Carries the semantic action of 丢: a thing leaving its place. The slanted 丿 over 去 makes a transparent "going away from you" compound. Filed under Kangxi #1 一 (yī), though no horizontal radical is visibly present.
Bottom 去 (to go, leave) - provides both the imagery and a faint phonetic echo. The compound reads as "something dropping and going away," matching 丢's senses: to lose (丢了钱包 lost the wallet), to drop (丢垃圾 toss trash), to put aside, to lose face (丢脸). Standalone 去 is one of the most common motion verbs.
Filed under radical 一 (yī, #1) by convention. 一 is not a separate component in 丢, so no strokes are highlighted.
