Enervate

/ˈen.ər.veɪt/ verb hard

To drain someone of energy, vitality, or strength.

The oppressive summer heat enervated the hikers long before they reached the halfway point of the trail.

Memory Trick

'E-' (out) plus 'nerv' (nerve or sinew) — to enervate someone is to strip out their nerve and strength, leaving them weak; don't mix it up with 'energize,' which means the exact opposite.
