覚え方のコツ Memory Tip
この「無気力な」は、体調が悪くて「だるい」という基本義とは分けて覚える。人が物事に関心や意欲を示さず、反応も弱い状態を表す用法で、apathetic「無関心な」や listless「気力のない」に近い。a lethargic response のように、態度や反応の鈍さを描くときに使える。名詞 lethargy は「無気力、沈滞」として関連づけると定着しやすい。
Put it opposite `energetic`. `Sleepy` is just wanting sleep, and `tired` is general fatigue, but `lethargic` suggests low energy, slow reactions, and no drive. It also connects well with the noun `lethargy`, so learning the pair helps it stick.
例文

だるい
(意味 2)解説 Definition
体調不良、寝不足、暑さなどで体が重く、眠気や疲労感があって動きにくい状態を表します。人や動物の一時的な体調について使われ、病気の症状を述べる文脈にもよく出ます。
If someone feels lethargic, their body feels heavy, slow, and low in energy. It is often used when a person or animal is tired because of illness, lack of sleep, heat, or general physical weakness. The word suggests not only fatigue but also slow movement and dull reactions.
覚え方のコツ Memory Tip
lethargic は energetic「元気な」の反対側に置くと覚えやすい形容詞。tired は広く「疲れた」、sleepy は「眠い」だけを表せるが、lethargic は体が重く、反応や動きまで遅くなる感じが強い。feel lethargic, become lethargic のように体調説明でよく使う。別エントリの「無気力な」より、ここではまず身体的なだるさに絞って覚えるとよい。
It helps to remember lethargic as the opposite of energetic. Tired is a broad word, and sleepy only means you want to sleep, but lethargic suggests that your whole body feels heavy and your reactions are slow. You often hear it in health-related phrases such as feel lethargic or become lethargic. For this word, focus first on physical sluggishness rather than mental apathy.
例文
I felt lethargic all day after getting only three hours of sleep.
3時間しか寝なかったので、一日中だるかった。
The dog looked lethargic and would not get up from the floor.
その犬はだるそうで、床から起き上がろうとしなかった。
Hot, humid weather can make people feel lethargic in the afternoon.
蒸し暑い天気だと、午後にだるく感じることがある。
lethargic の語源・成り立ち Etymology
lethargic はギリシャ語 lethargos 由来で、lethe「忘却」+ argos「動かない」に形容詞語尾 -ic が付いた語です。lethargy や Lethe と同根で、ただ疲れたのでなく「意識が沈み反応できない」感じまで語源に刻まれています。
Lethargic comes from Greek lethargos, through Latin and French, with the English adjective ending -ic. The Greek word is linked to lethe "forgetfulness" and argos "inactive" or "idle." This gave the sense of a heavy, dull state in which a person seems slow, sleepy, or unresponsive. Related words include lethargy and Lethe.
