Morphology

reliable = rely (transparent) = rely + able

Standard adjective formation from the verb 'rely' + suffix '-able', meaning 'able to be relied on'.

Etymology

The word reliable comes from the verb rely, which once meant 'to bind' or 'tie', so imagine your trust tied to that person. That's why a reliable person or thing is one you can trust or depend on.
