How to pronounce 面?


For example in the phrase "物の面", how would you _commonly_ pronounce 面? I see
three possibilities: めん、つら、おも. Which one (or ones) are commonly used?

Example sentence: "人の手の指先の内側にある、多くの細い線からできている模様。また、その模様が物の面についたあと。" (指紋の定義)




In your example, 面 is read **めん** because it means "surface (of a thing)".

As for when to use the other readings, see: [面 and 顔
