Frivolously means in a silly, careless, or not serious way. It is often used when someone treats an important matter too lightly or focuses on unimportant things.
覚え方のコツ Memory Tip
まず形で覚えると楽です。frivolously は frivolous（軽薄な）+ -ly（〜に）で、「軽薄な態度で」がそのまま副詞になった形。seriously の反対側に置き、物事を重く受け止めず、冗談半分・表面的に扱う場面を思い浮かべると残りやすいです。speak frivolously, spend money frivolously のように、発言やお金の扱いが shallow で irresponsible だという含みが出やすい語。casually よりも『真面目さや慎重さが欠ける』という批判的な響きが強い点をセットで覚えると使い分けしやすくなります。
Break it into `frivolous + -ly`. If you know the adjective, the adverb is easy: it means doing something in a `frivolous` way. Put it next to `seriously` as a contrast word in your memory. Phrases like `speak frivolously` or `spend money frivolously` help show its critical tone.
例文

彼は深刻な問題について軽薄に話した。
Frivolously spending money is irresponsible.
お金を軽薄に使うことは無責任である。
She regretted the decision she had made frivolously.

frivolously の語源・成り立ち Etymology
frivolously は frivolous＋-ly。frivolous はラテン語 frivolus「取るに足らない」にさかのぼり、さらに「砕けやすい・崩れた」感覚を含む語根 friare と結びつく。friable も同根で、中身が崩れて軽いという像が「軽薄に」へつながる。
Frivolously comes from frivolous with the adverb ending -ly. Frivolous goes back to Latin frivolus, meaning "silly" or "worthless," and it may be linked to a root suggesting something broken or crumbly. That idea of something lacking solidity developed into the sense of acting in a light or careless way; friable is from the same wider family.
