Collocations
Pro Tip
Avoid the 'Nervous' Trap
Do not use 'enervated' to describe anxiety. If you are worried, use 'nervous'. If you are tired and weak, use 'enervated'. Remember: 'enervated' = 'no energy'.
Gold Rule
Formal Register Only
Use 'enervated' in writing or formal speech. In casual conversation, 'tired' or 'drained' is more natural.
Word Origin
From Latin 'enervatus', past participle of 'enervare' meaning 'to deprive of strength or vigor', from 'e-' (out) + 'nervus' (sinew, nerve, strength).
Usage Notes
This is a classic 'false friend' for learners. Because it contains 'nerv', many assume it means 'nervous' or 'anxious'. It actually means 'weak' or 'tired'. It is a formal word, rarely used in casual conversation.
