Surface Forms

Morphology

one + and + only

The meaning 'the only one' is directly and predictably derived from combining 'one' (a single unit) with 'only' (indicating uniqueness), with 'and' serving as a simple connector/emphatic linker. This compositional pattern follows normal English semantics and is immediately comprehensible to a B1 learner who knows the constituent words.

Etymology

One and only comes from the simple image of a single person or thing that stands alone, clearly one and only in a room or on a stage so everyone notices them. That's why it means 'unique' or 'the only one'.
