覚え方のコツ Memory Tip
confidentially は confidential（機密の）+ -ly と見れば、副詞化の形がまず頭に入る。confide in someone（打ち明ける）を知っていると、『信頼できる相手にだけ話す感じ』から意味がつながる。confident（自信のある）や confidence（自信）とつづりが似るが、こちらは『秘密保持』の方向なので混同注意。keep it confidential, speak confidentially など、公開せず限られた相手にそっと伝える場面ごと覚えると残りやすい。
See the structure: `confidential` + `-ly`. If you know `confide in someone`, that gives the feeling of speaking only to a trusted person. It also helps to contrast it with `confident`, which is about self-belief, not secrecy.

confidentially の語源・成り立ち Etymology
confidentially は confidential + -ly から成り、confidential はラテン語 confidere「信頼する」にさかのぼります。con-「共に」+ fidere「信じる」なので、「信頼して打ち明けるように」が転じて「内密に」となり、confide や confidence が関連語です。
Confidentially comes from confidential plus -ly. Confidential goes back to Latin confidere, meaning "to trust," from con- "with" and fidere "to trust" or "believe." The sense moved from speaking in trust to speaking privately, which led to the modern idea of doing something in a secret or private way; related words include confide and confidence.
