IPA: /vɪkˈtɔːrɪəs/
KK: /vɪkˈtɔrɪəs/
Describing someone or something that has won a competition or battle.
The team was victorious after a hard-fought match.
Victorious → It is formed from "victor" (from Latin "victor", meaning conqueror or winner) and "-ious" (meaning full of or having the qualities of). The word "victorious" means having the qualities of a conqueror or being full of victory.
Think of a 'conqueror' ('victor') who is 'full of' ('-ious') success — that's what it means to be victorious.
