This is the exact opposite of my experience- I think wordlessly with both abstract and concrete things, and hunting for words might work for the concrete things occasionally, since they are mostly the same, but for almost all abstract things there simply does not exist any word even close to what I want to say, so surrender - the hard kind, accepting defeat and humiliation, like that class scene in MoR - and making do with unbearably clumsy, confusing and muddled metaphor is exactly what I have to learn in every case I don't know the exact mathematical notation to formalize my thoughts.
