A reason that appears real or appropriate but in fact is not gives rise to the fallacy hetvabhasa. With which term is this fallacy connected?

The fallacy hetvabhasa is connected with the middle term.

The hetu is the reason of the inference and functions as the middle term.

A hetvabhasa is a hetu that looks like a valid reason but is not.

Since the defect lies in the reason, it attaches to the middle term.

A faulty middle term thus produces a merely apparent proof.
