relapsing-remitting

The term is a modern medical compound, built from two classical participles to describe a clinical pattern. The first element, 'relapsing', originates from the Latin relabi, meaning 'to slide or fall back', a vivid metaphor for the return of disease symptoms. The second element, 'remitting', derives from Latin remittere, meaning 'to send back' or 'to slacken', conveying the idea of symptoms easing or withdrawing. Combined, these two participles create a precise, descriptive adjective that logically encapsulates the cyclical nature of the condition: a falling back into illness followed by a sending away or lessening of its severity.

Structure: relaps (to fall back) + ing (present participle) + remit (to send back, to abate) + ing (present participle) - relaps: From Latin relapsus, past participle of relabi ('to slide back'), from re- ('back') + labi ('to slip, fall'). In this compound, it functions as the core meaning of 'falling back' into illness. - ing: A suffix from Old English -ende, forming present participles, here turning the verb into an adjective. - remit: From Latin remittere ('to send back, slacken, abate'), from re- ('back') + mittere ('to send'). In this compound, it functions as the core meaning of 'sending back' or 'lessening' the disease activity. - ing: A suffix from Old English -ende, forming present participles, here turning the verb into an adjective.
