sorry, the norm is no punctuation in crossword clues, I was following a pattern.
With punctuation:
Reinforcements - here comes the ???????, rhymes with '???????' will be the next pointer.
The answer rhymes with Valerie.
Here comes the ??????? which rhymes with Valerie.
???? Grant - famous film star, with a shortened girl's name in the middle, giving a colloquial name for reinforcements.
Comms failure!
Slight knocking on the water regulator (3)
was a loose illustration of the type of clue, where the answer, obviously "tap", is a word for both parts of the clue.
"Tap" is nothing to do with this one, but the answer ( which is one word) is again connected to both parts of the clue.
I suppose lawyer with a nice sheen (4)
or
Made a noise on the tree (6) (better probably)
are similar enough
