TOEIC Link Part 5: enervate versus energize
Enervate and energize both start with the same syllables and both concern energy, so test-takers assume they point the same way — but they are near opposites. Enervate is a verb meaning to drain of strength, vitality, or energy. Energize is a verb meaning to fill with energy, activity, or enthusiasm. Part 5 drops one into a sentence where the polarity of the blank is the whole question. For the wider set of look-alike traps, start with the commonly confused word pairs master index.
The core rule: drain versus invigorate
- enervate = to weaken, exhaust, or sap of vitality (verb). The relentless heat enervated the crew long before the shift ended. / Endless meetings enervate the team and leave no energy for real work. It answers what wears down or drains? and describes a loss of strength. Link enervate to exhaust and sap: it takes energy away.
- energize = to give energy, drive, or enthusiasm to (verb). The new manager energized the department with clear, achievable targets. / A short break can energize workers for the afternoon. It answers what fills with energy? and describes a gain in drive. Link energize to invigorate and galvanize: it puts energy in.
The key difference: enervate removes energy, while energize adds it. A schedule that enervates staff leaves them depleted; a leader who energizes staff leaves them motivated. If the blank describes draining or weakening, choose enervate; if it describes invigorating, choose energize.
Why Part 5 likes this pair
Because both verbs open with ener- and both relate to energy, the shared look invites a wrong guess. If the blank describes something that wears people down or saps their vitality, you need enervate. If the blank describes something that fires people up or gives them drive, you need energize.
The long overnight flights had __ the sales team, and their afternoon pitch fell flat.
A word describing a loss of energy and vitality needs enervated.
The redesigned bonus plan __ the field reps and lifted quarterly output.
A word describing an infusion of drive needs energized.
Spotting the clue
Decide whether the blank takes energy away or gives energy:
- Is the subject draining, exhausting, or weakening someone or something? → choose enervate (the humidity enervated them, an enervating routine, feeling enervated).
- Is the subject invigorating, motivating, or activating? → choose energize (the speech energized the crowd, an energizing goal, newly energized).
A quick test: can you replace the blank with drain or sap, as in the heat drained the crew? Then it is enervate. Can you replace it with invigorate or fire up, as in the plan invigorated the reps? Then it is energize. Watch the surrounding tone too — enervate travels with fatigue, heat, and tedium, while energize travels with motivation, momentum, and enthusiasm. Because both are action verbs whose polarity is easy to misjudge, this pair sits alongside other verb traps such as deprecate versus depreciate.
Common Part 5 patterns
- Anything about draining or weakening wants enervate: the heat enervated them, an enervating commute, left enervated.
- Anything about filling with drive wants energize: the news energized the team, an energizing kickoff, feel energized.
- Context cue: fatigue, heat, or tedium leans enervate; motivation, momentum, or enthusiasm leans energize.
If the blank describes draining strength away, choose enervate. If it describes pouring energy in, choose energize.
Quick recap
- enervate — to drain of strength or vitality; the subject ends up weaker.
- energize — to fill with energy or enthusiasm; the subject ends up stronger.
- Decide first: is the blank removing energy (enervate) or adding it (energize)? Their shared spelling hides opposite meanings, so the polarity test settles it.
