This might help someone's understanding, or might not ...
It took me several (self-taught) decades to realize that, in most situations that applied to me, the stated "diminished" chord was simply a one-fret-up movement of the preceding major chord's root note, leading into (some note of) the following chord. In other words, the other notes (3 & 5) of the preceding major chord don't change or move at all, they simply stay in place while the root implies upward motion.
One might think that the chord doesn't get "diminished" - its "other" notes just sit there (from the prior major chord) while its root moves toward the next goal! (PLEASE realize that this is just my own unorthodox thinking!!)
In David's example of G to G# to A, that would be movement (in key of G) from the I chord up toward the IIm. In practice, that "goal" A note is just as often the 5 note of the V chord (D7 in key of G). Hey, still sounds good to me!
In my (relatively limited) musical word, that realization went a long way to de-mystifying the occasional "dim".
