Thanks, Aristo. As usual, my problem was with the forest vs the trees.
Parsed it as a Combination clue (trees):
? (joins up or gets) + A + B + IN + E(nglish)
instead of a Hidden clue (forest): joins up [hidden] = get(S A B IN E)nglish
Duh !
26A - putting the Reversal indicator between two possible defs is always a zinger.
Thanks for the info re the architect. I'll read it tomorrow.
I spend too much time in Wiki jumping from from one link to another, but there's so much esoteric stuff there.
Cheers.
