in addition to の語源・成り立ち Etymology
additionはラテン語additio、動詞addere（ad-＝〜へ＋dare＝与える→付け加える）から。「何かに向けて与える→追加する」が原義。関連語：add（加える）、additive（添加物）。前置詞toと組み合わせ「〜に加えて」と累加を示す。
"Addition" comes from Latin "additio," from the verb "addere," meaning to add or put to. That verb is built from "ad-" meaning "to" and "dare," meaning "give," so the older sense was like giving something to something else. In the phrase "in addition to," this developed into the meaning of including something extra besides what is already there. Related English words include "add" and "additive."
