奖

Bottom 大 - the indexing radical for the simplified form, replacing traditional 獎's 犬 (dog, which originally meant 'incite a hound to chase' in the prize-bestowal context). The 1956 swap from 犬 to 大 makes the modern character read straightforwardly as 'a big reward.' Friendly redesign rather than old etymology.

Top-left 丬 - historically the left half of 爿 (split bed-board). Supplies the sound element (jiāng → jiǎng with tone shift) for the same phonetic series 将 jiāng/jiàng (general/will), 浆 jiāng (paste), 桨 jiǎng (oar). Pure sound carrier in the simplified form; the traditional 獎 had the fuller 將-over-犬 structure.

Top-right 夕 - replaces traditional 獎's 寸 (hand offering) above the dog. Visual filler in the simplified form; the 'evening' meaning isn't really active. Loosely you can read it as 'evening prize ceremony,' but treat 夕 here as a graphic substitute completing the upper half of the silhouette.
