I want to start by saying that I am pretty new to syntax (and linguistics in general for that matter) but I've been trying to wrap my head around x-bar theory and generative grammar in the last weeks. Also, English is not my first language, so I apologize for any mistakes I might make.
Recently, I've come across the concept of split infinitives and, as I always do, tried to build a syntax tree to improve my understanding of the subject. Since I had already learnt about complementizer phrases and so on, I figured I'd give it a try:
"I want to really immerse myself in the performance."
I know that the feature marks should be surrounded by square brackets, but sadly this software doesn't allow me to do that. My decision to write out some branches while not doing so for others is also a bit arbitrary.
Anyway, any feedback on wheter or not this syntax tree is "correct", at least as far as generative grammar goes, would be greatly appreciated! I am aware that x-bar theory isn't the most recent theory anymore but I still hope that I can pick up some useful insights by studying it a bit.
