Past tense of convalesce; recovered from illness or surgery by resting and gradually regaining strength.
From Latin 'convalescere,' combining 'con-' (intensifier) and 'valescere' (to grow strong), which itself comes from 'valere' (to be strong). The word entered English in the 17th century to describe the recovery period after serious illness.
Before modern medicine, the word 'convalescence' was so important that rich people had entire 'convalescent homes' in seaside or mountain towns—they understood that recovery required time, rest, and fresh air, which we're only now confirming with neuroscience.
