Mark's explanation hits lots of good points.
I have a good "feel" for what works, and understand where/why certain passages "fit."
I got a lot from one college music theory class, and would be a stronger player if I had continued. Same with the piano lessons Mom paid for until they didn't satisfy my need for "cool." Who knew? Hindsight, and all that
Lacking the ability to articulate in words leaves me with "let me show you," and "please show me again, SLOWLY." A couple of repetitions is usually enough, then the "light comes on." Adequate for casual purposes, but like Inspector Harry Callahan said, "a man's got to know his limitations."
