Morphology

day + by + day

The meaning is directly compositional: repeating 'day' with the preposition 'by' signals 'one day after another' or 'each day', so a learner who knows 'day' and the basic use of 'by' can infer 'gradually, as time passes'. This repetitive construction has clear cross-linguistic parallels (e.g. Spanish 'día a día', French 'jour après jour') and follows standard English patterns, making it immediately comprehensible to a B1 learner.

Etymology

The phrase day by day comes from the simple image of watching time one day at a time, like marking each day on a calendar and seeing small changes build up. So it means 'gradually' or 'with each passing day'.
