Morphology

son + of + a + gun

The affectionate/exclamatory meaning of 'son of a gun' cannot be deduced from the literal meanings of 'son' and 'gun' — there is no straightforward compositional logic that yields 'tough or admirable person' or an exclamation of surprise. This expression is idiomatic and euphemistic, so a B1 learner who knows the individual words would likely not infer the phrase's conventional meaning without prior exposure.

Etymology

Son of a gun may come from life on old warships: when sailors had babies on board, births sometimes happened between the ship's guns, so the child was literally a son born by a gun. That's why the phrase became a friendly, slightly 'cheeky' name for someone 'tough' or clever and is used to show 'surprise' or 'admiration'.
