Convalesce is formed from "con-" (meaning together) and "valescere" (meaning to be strong or to be well). The word describes the process of becoming strong or well again after an illness, emphasizing the idea of recovery together with health.
Think of becoming 'strong' ('valescere') again 'together' ('con-') after being unwell — that's what convalesce means.
