Morphology
hard-and-fast + rule
The phrase 'hard-and-fast' uses 'hard' (firm) and 'fast' in the sense of fixed/secure rather than quick, so the literal constituents only partially hint at rigidity. A B1 learner who knows the words might guess a sense of firmness but would likely not predict the conventionalized meaning 'inflexible, unchangeable' without prior exposure, so the expression is only partially transparent.
Etymology
Hard-and-fast rule comes from the image of something held so tightly it is hard and fast, like a rope tied tight and stuck in place. So, it means a rule that is 'fixed' and 'cannot be changed'.
