The Chinese word "遗忘" is formed through the semantic combination of two characters: "遗", which carries the meaning of losing, leaving behind, or omitting, and "忘", which directly signifies forgetting. When merged, these characters create a compound word where "遗" amplifies "忘" by introducing the nuance of loss or abandonment, thus collectively conveying the idea of forgetting as a process of letting memories slip away or fade into oblivion. This formation reflects a conceptual blend where both elements contribute to a unified meaning that emphasizes the permanent or involuntary nature of forgetting.
