Reenergize

Part of speech: verb

Definitions

1. To restore energy or enthusiasm to someone or something, renewing their strength or vigor
2. To refresh or invigorate, giving new energy or motivation after fatigue or decline
3. To reinvigorate by replenishing strength, spirit, or activity levels in a person or thing

Etymology: "Reenergize" is simply the prefix "re-", meaning "again" or "back," attached to "energize." The base verb "energize" comes from "energy," which traces to the Greek "energeia," meaning activity or operation, built from "en" (in) and "ergon" (work). So the whole word means, in effect, to put work or activity back into something that has lost it. The prefix does most of the work here. English has long attached "re-" to verbs of this kind, so "reenergize" follows the same pattern as "reinvigorate" or "revitalize," adding the sense of restoration to an existing action. Because "energize" itself describes supplying energy, "reenergize" describes supplying it again after it has been drained, whether the subject is a tired person, a stalled project, or a flagging team.

Synonyms: revitalize, refresh, renew, invigorate, regenerate
