Surface Forms

how so main

Morphology

how + so

The meaning 'used to ask in what way or for what reason' is directly derivable from combining 'how' (in what way) with 'so' (in that way); it literally asks 'in what way is that so?'. This is a compositional, cross-linguistically common pattern and would be understandable to a B1 learner who knows both constituent words.

Etymology

How so may come from the simple idea behind the words how, meaning 'in what way', and so, meaning 'like that'. It is like pointing at what someone said and asking 'how is that?', so today people use how so to ask someone to explain or show why something is true.
