Morphology

fringe + theory

The meaning is directly compositional: 'fringe' denotes marginal or peripheral, and 'theory' denotes a set of ideas, so 'fringe theory' naturally means a theory on the margins of mainstream thought. This adjective+noun pattern is common cross‑linguistically and follows normal English composition, so a B1 learner who knows both words would likely infer the intended meaning.

Etymology

Fringe theory comes from the image of a fringe — the loose edge of a cloth — and theory, which means an idea. One popular image is an idea at the 'edge' of what experts accept, not in the centre, so it means an idea outside the 'mainstream' and often not well supported.
