conductive
導電性の
解説 Definition
電気や熱などを通しやすい性質を持つ。物質が電流をよく通すことができる状態。
Conductive means able to let heat or electricity pass through easily. It is often used in science and engineering to describe materials such as metal. The opposite idea is shown by words like insulating or non-conductive.
覚え方のコツ Memory Tip
conduct を「導く・運ぶ」、conductor を「電気を通すもの」と知っていれば、conductive は「何かを通して先へ運べる性質がある」とつながります。-ive は「〜する性質の」。金属は conductive、ゴムやプラスチックは opposite の insulating と対比すると定着しやすいです。a conductive material, conductive ink, thermally conductive などの形でよく出て、conduct の「行動する」意味よりも「伝える・通す側の性質」に意識を置くと混同しません。
Link it to `conduct` and `conductor`. Here the idea is not behavior, but carrying something through, such as electricity or heat. It is easy to remember if you contrast it with `insulating`: metal is often `conductive`, while rubber is not.

conductive の語源・成り立ち Etymology
conductive はラテン語 conducere に由来し、con-「共に」+ ducere「導く」+ -ive「〜する性質の」から成ります。conductor や conduct も同根で、電気や熱を「向こうへ導く性質」が導電性という意味にそのままつながります。
Conductive comes from Latin conducere, built from con- meaning "together" and ducere meaning "to lead." In English it was formed with the adjective ending -ive, meaning "having the quality of." The core idea is something that leads or carries something onward, which fits its later technical use. Related words include conduct and conductor.
