Morphology
The phrase is compositionally built from 'caustic' (corrosive, burning) and 'potash' (a potassium compound), so a learner who knows both words can infer it refers to a corrosive potassium substance. While the exact chemical identity (potassium hydroxide) is technical, the general meaning 'a strong, corrosive potassium-based chemical' is transparently derivable from the constituents.
Etymology
Caustic potash comes from two parts: caustic, meaning 'burning' or able to burn the skin, and potash, an old name for salts made by soaking wood ashes in pots. So the name gives a clear image of a very strong, skin-burning chemical made from ash salts, which is why today it refers to potassium hydroxide used in industry and farming.
