Morphology

back + to + square + one

The element 'back to' clearly signals returning and 'one' suggests the first or starting point, so a learner who knows the words could plausibly infer a sense of returning to the start. However, 'square one' functions as a conventionalized unit (likely from board‑game usage) where 'square' is not literally a plaza, making the phrase partially idiomatic and not fully predictable without prior exposure.

Etymology

The idiom back to square one may come from old board or children's games where the start was a square marked one, and if you failed you had to go back to that first square. So, it means 'to begin again' after a failure.
