解説 Definition

覚え方のコツ Memory Tip
まず attentive を押さえると覚えやすいです。attention と同じ仲間で、「注意を向けている」状態が attentive。その前に否定の in- が付くと inattentive で「注意が向いていない」。careless が「不注意で雑」という広めの語なのに対し、inattentive は授業・会話・運転などで「注意を払っていない」感じが中心。an inattentive student, listener, driver の形で場面ごと覚えると定着します。
Start with `attentive`, which is from the same family as `attention`. Then add the negative prefix `in-`, so `inattentive` becomes "not paying attention." It often appears in phrases like `an inattentive student`, `listener`, or `driver`, so remember it through situations where someone should be focused but is not.

inattentive の語源・成り立ち Etymology
inattentive は in-「否定」+ attentive。attentive はラテン語 attendere「心を向ける」に由来し、ad-「〜へ」+ tendere「伸ばす」が核。つまり inattentive は意識が伸びない状態で、attention も同じ tend- の仲間。
Inattentive combines the negative prefix in- with attentive. Attentive comes from Latin attendere, built from ad-, "to," and tendere, "to stretch" or "direct." The idea is of not stretching the mind toward something, and related English words include attention and tense.
