Terms are theory-laden.
Theory commits to particular ontologies.
I guess I don't understand this either. Terms are parts of language. The claim that all terms of a language are theory-laden is so widely accepted and so ingrained in my own views, that I had to consult my library to find the most useful references for you. The thesis was most famously argued for by Quine and Sellars. The conclusion is that for a term to be meaningful at all, it must also be theoretical.
