Type of clue receiving much credit in word puzzles (9)

'puzzles' is the definition.
(I know this)

'type of clue receiving much credit' is the wordplay.
'type of clue' becomes 'across' (in a crossword).
'receiving' means one lot of letters goes inside another.
'much' means to remove the last letter (much but not all of the word).
'credit' becomes 'tick' (on tick can mean purchased on credit).
'tick' with its last letter taken away is 'tic'.
'across' going around 'tic' is 'ACROSTICS'.

'in word' acts as a link.
This may not be right. Some or all of it may belong to another bit of the clue.
