可以想成「一群人或東西被分成兩邊時，比較大的那一邊」。majority 的核心畫面比較像「超過一半、人比較多的那一堆」。這個「較大的那一份」的想法可以延伸到投票（票多的一方）、公司股份（股份過半的一方），也以另一條路通到「年紀已經長到完整成人」的法定成年。From the word’s history
From Latin maior 'greater' (the comparative of magnus 'great') + -ity; literally 'the state of being the greater part'.
源自拉丁文 maior「較大的」（magnus「大」的比較級）加上 -ity。字面就是「成為較大那一部分的狀態」，與核心畫面「比較大的那一邊」完全吻合。
