"What is the _ behind this?"
My mom and I were discussing some sort of science-related topic (as I unsurprisingly forgot what it was even if we were talking five minutes ago). I said, "What is the taxidermy behind this?", and she started explaining what "taxidermy" meant to me. Of course, I'm no English specialist, as I'm a teenage minor, so I have no idea what that word meant. I started to wonder what the word I actually meant was, since I heard the phrase, "What is the taxidermy behind this?" somewhere online (for clarification, we searched Google and Google said it was some sort of autocorrect).
The word I'm looking for is science-related, but it's not typical vocabulary like "reason", "method", "thought process", etc.. It's advanced vocabulary, and, iirc, it started with either a "T" or "S" (if not, one of those letters are somewhere embedded in the word). It wasn't "situation", as it was a more complex word than that.
Please lmk if you have any suggestions!!
p.s. I'm on computer, so I apologize for any spelling mistakes
