覚え方のコツ Memory Tip
この項目の investigational は、一般的な「調査の」ではなく、医薬品・治療法などがまだ承認前で研究・試験の対象になっている状態を表します。investigate（調べる）から「有効性や安全性を確かめている段階」と考えると覚えやすいです。特に investigational drug, investigational treatment, investigational study の形で出やすく、「新しい」「有望な」ではなく「まだ正式使用前」という点を強く意識しましょう。
Keep it connected to `investigate` and `investigation`, not `investment`. The ending `-al` often makes an adjective, so this word feels like `related to investigation`. You will often meet it in fixed medical phrases like `investigational drug`, which helps the form stay in memory.
例文
The investigational drug showed promising results in early trials.
その研究中の薬物は初期段階の試験で有望な結果を示しました。
Patients can participate in investigational studies with informed consent.
患者はインフォームド・コンセント下で試験的研究に参加できます。
The investigational treatment requires further testing before approval.
その研究中の治療法は承認前にさらなるテストが必要です。
調査の
(意味 2)解説 Definition
調査や捜査に関係することを表す形容詞です。苦情、事件、問題の原因などを調べる手続き・段階・記録について、やや書き言葉で使われます。
Investigational describes something connected with an investigation or formal inquiry. It is often used for procedures, stages, records, or reports that are part of finding the cause of a complaint, case, or problem. The word sounds slightly formal and is more common in written contexts than in casual conversation. It does not usually mean simply curious or questioning.
覚え方のコツ Memory Tip
investigational は investigate（調査する）+ investigation（調査）+ -al（〜に関する）と分けると、「調査に関する」という形容詞だと捉えやすいです。似た investigative も「調査の」ですが、新聞・報道では investigative journalism のように investigative の方が一般的。investigational は phase, process, record など、調査手続きや調査段階を表す少しかたい文脈で覚えるとよいです。医療の「研究中の」とは別義です。
You can remember investigational by breaking it into investigate + investigation + -al, which gives the idea of "related to an investigation." A close word is investigative, but investigative is more common in phrases like investigative journalism. Investigational often appears in slightly formal contexts with words like phase, process, record, or report. Be careful not to confuse this sense with the medical meaning "under study."
例文
The committee reviewed the investigational report before making its final decision.
委員会は最終決定の前に調査報告書を確認した。
Several investigational steps were taken to find the source of the error.
その誤りの原因を突き止めるために、いくつかの調査段階が取られた。
The lawyer asked to see all investigational records related to the complaint.
弁護士はその苦情に関するすべての調査記録の閲覧を求めた。
investigational の語源・成り立ち Etymology
investigate はラテン語 investigare「足跡を追って調べる」からで、in-「中へ」+ vestig-「足跡」+ -tional。vestige や investigate が同根で、『跡をたどって確かめる段階の』感覚が「研究中の」につながります。
Investigational comes from investigate, which goes back to Latin investigare, meaning "to trace out" or "search into." It is linked to vestigium, meaning a footprint or track, so the original image is following signs or tracks. From that idea, investigational came to describe something still being examined or studied.
