闘志: spirit retained after a conceded point and fueled by a performance
Compare maintained fighting spirit with the fire metaphor, keeping final results and subject information within each sentence.
Spirit retained after conceding a point
闘志 (とうし) means fighting spirit. 「一点を失っても選手たちの闘志は消えなかった。」 means “Even after conceding a point, the players did not lose their fighting spirit.” The players did not lose their fighting spirit after conceding a point.
The negation in 消えなかった preserves retained spirit, without a final match result.
The metaphor in 闘志に火をつけた
「相手の力強い演技がかえって闘志に火をつけた。」 means “The opponent's powerful performance only fueled her fighting spirit.” The opponent's powerful performance fueled fighting spirit.
火をつけた is figurative here; it does not report a fire or anger.
