不十分に
解説 Definition
不十分にとは、必要とされる量や質に達していない、または不完全な方法で何かをすることです。適切ではない程度や水準を示す副詞です。
Inadequately means in a way that is not enough or not good enough for a purpose. It is used when something is done with too little care, skill, amount, or preparation. It often shows that a result does not meet the needed standard.
覚え方のコツ Memory Tip
まず `adequate` を「必要ラインは満たす＝十分な」と覚えると、`in-` が付いた `inadequate` はその反対で「十分でない」。さらに `-ly` で副詞化して、「不十分なやり方で」が自然に出せます。`inadequately prepared / trained / equipped / addressed` のように、準備・訓練・設備・対処が足りない場面でよく使われます。`insufficiently` と近いですが、`inadequately` は量だけでなく質や対応のまずさも含みやすい点が記憶のフックです。
Start with `adequate`, which means good enough or enough for the need. Add `in-` and it becomes the opposite, then `-ly` makes it an adverb: done in a not-good-enough way. Common pairs like `inadequately prepared` or `inadequately trained` help fix it in memory.

inadequately の語源・成り立ち Etymology
in-「否定」+ adequate + -ly から成る副詞。adequate はラテン語 adaequatus「等しくされた、十分な」にさかのぼり、ad-「〜へ」+ aequus「等しい」が語源で、「十分な水準に達せずに」が原義。関連語は equal, equate。
This adverb is built from `in-` meaning "not," `adequate,` and `-ly.` `Adequate` comes from Latin `adaequatus,` meaning "made equal" or "made sufficient," from `ad-` plus `aequus` meaning "equal." The idea developed from "brought up to an equal level" to "good enough," so `inadequately` means in a way that does not reach that level. Related English words include `equal` and `equate.`
