Morphology

have + a + legs + to + stand + on

The phrase maps a concrete image (literally having a leg to stand on as physical support) onto an abstract sense of support or justification, so a learner who knows the words can often infer the metaphorical meaning. However, this requires making a figurative extension rather than a direct compositional reading, so the sense is partly predictable but not fully obvious without prior exposure.

Etymology

The idiom have a leg to stand on comes from the simple image of standing: if you do not have a leg to stand on, you cannot stay upright and you have no support. So the phrase now means 'to have a good reason or support'.
