What does resolvent mean?
A resolvent is something that resolves, settles, or dissolves a problem, obstruction, or swelling. The adjective is chiefly associated with medicine, where it describes a treatment or substance capable of reducing inflammation or making a swelling subside. It can also apply more broadly to actions or measures that end a dispute or clear away an obstacle. As a noun, a resolvent is typically a medicine or chemical substance with such a resolving effect. Today the word is uncommon and has a learned, technical tone, but it remains useful because it conveys more than simple dissolution: a resolvent not only causes material to disperse but can also make a difficult condition improve or come to an end. Its specialized medical sense distinguishes it from the more general modern term solvent, which primarily denotes a substance in which something dissolves.
