Someone or something that disentangles; a person who clarifies confusing situations or frees things from tangles.
From disentangle + -er, the common English suffix that creates agent nouns (one who does the action). The -er suffix is one of the oldest and most productive in English.
A 'disentangler' could be a person who helps solve complex problems—therapists, mediators, and puzzle solvers are all disentanglers in their own way, making this a genuinely useful word for describing helpful people.
