Morphology
A B1 learner who knows 'plain' as 'simple/not containing extras' plus 'flour' will likely infer that 'plain flour' is flour without added ingredients, so the basic idea is derivable from the parts. However, the specific technical nuance — that it lacks a raising agent (and regional naming differences like UK 'plain flour' vs US 'all‑purpose') — is somewhat lexicalized and may not be fully predictable, so it isn’t fully transparent.
Etymology
Plain flour comes from calling the word plain to mean 'simple' or 'not mixed', showing the flour has nothing added. So the name means 'flour without a raising agent', which is why recipes use plain flour when they add baking powder or other leavening themselves.
