Morphology

soy + flour

The compound is directly compositional: 'soy' (soybeans) + 'flour' (fine powder from grinding) yields a fine powder produced from soybeans, so a B1 learner who knows both words can infer the meaning. This is a regular noun+noun formation found across languages (e.g., 'harina de soja', 'farine de soja'), reinforcing its predictability and transparency.

Etymology

The noun soy flour comes from a simple idea: soybeans are ground into a fine powder to use like regular flour. Here soy means the soybean and flour means the fine powder, so the name shows it is a ground soybean product used 'as an ingredient' in baking and cooking.
