思いがけず
解説 Definition
予想に反して、または思いもよらない方法で何かが起こること。突然で、準備されていない様子を表現します。
Unexpectedly means in a way that was not planned or not thought likely to happen. It is used when something surprises people because it is different from what they expected. The word can describe both good and bad situations.
覚え方のコツ Memory Tip
まず expected「予想された」を軸に置くと覚えやすいです。un- が付くと「予想されない」→ unexpected、さらに -ly で副詞化して unexpectedly「予想外に」。expected / unexpected / unexpectedly と3段で並べると形が頭に残ります。suddenly が単なる「突然」なのに対し、unexpectedly は「予想に反して」が中心。unexpectedly win, unexpectedly found, unexpectedly quiet のように、結果や展開が意外だった場面でよく使います。accidentally「うっかり」とは別語なので混同しないのがコツです。
Build this word in parts: expected, then unexpected, then unexpectedly. That makes it easier to remember the form and meaning together. Unlike suddenly, unexpectedly focuses on surprise, not just speed.

unexpectedly の語源・成り立ち Etymology
unexpectedly は un-「否定」+ expected + -ly で、expect はラテン語 ex-「外へ」+ spectare「見る」に由来します。spectator や inspect と同じ spect- を含み、「先を見ていたのに外れる」から「思いがけず」になる語です。
Unexpectedly is made from un- + expected + -ly. Expect comes from Latin ex- "out" and spectare "to look," the same root seen in spectator and inspect. The basic idea is of looking ahead, so unexpectedly means in a way that does not match what was looked for or anticipated.
