Can any technical term be used metaphorically? For instance, can I use the word assimilable which means capable of being absorbed and incorporated into body tissue (because it's broken down into a form that can be absorbed) in a sentence like "Calculus is not readily assimilable by students without appreciable Mathematics background"
I'm also wary because technical terms (assimilable belongs in Biology) are not always popular.
I know technical terms are already being used metaphorically. One may even use these words without realizing they've been adapted from a certain discipline for everyday use. Their derived meanings seem denotational because of its pervasive use. (I know I won't be forgiven for my lack of examples, they're not coming to mind atm. But I'm praying you get the picture.)
So my question is about the aptness of using these less common technical terms. I know I risk my audience not comprehending me when I use them, but surely there was a point in time where these very familiar (technical) expressions we use today weren't as commonplace as they are now. I hope someone understands me :-)
