覚え方のコツ Memory Tip
weight「重みを付ける」に -ed を付けた過去分詞由来の形容詞で、発音は /ˈweɪtɪd/。単に heavy「物理的に重い」ではなく、weighted average、weighted score、weighted system のように、項目ごとの重要度を数値へ反映させた状態を表します。「重要な項目ほど大きな重りを載せる」と捉えます。
Start with weight as the verb “to give importance or influence,” then add -ed to form weighted. It is pronounced with an extra syllable at the end, /ˈweɪtɪd/, because the base ends in /t/. Imagine placing larger numerical weights on more important items. In a weighted average, values do not all contribute equally; those assigned greater weight affect the result more. Learn it through common combinations such as weighted average, weighted score, and weighted system. Unlike heavy, weighted here usually describes calculated importance rather than physical mass.

weighted の語源・成り立ち Etymology
weighted は weight「重さ」に形容詞・過去分詞を作る -ed が付いた語で、weight は古英語 gewiht、さらにゲルマン祖語系に由来します。文字どおり「重みを与えた」が「重み付けされた」。関連語は weigh, weighty。
Weighted is the past participle and adjective formed from the verb weight plus -ed. Weight comes from Old English gewiht and belongs to a Germanic word group associated with heaviness and weighing. The literal act of adding physical weight developed a figurative and mathematical use: assigning different degrees of importance or influence. This figurative sense underlies expressions such as weighted average and weighted score.
