Wild oregano tip for regular titbit of pasta? (9)
I believe the answer is:
manicotti
'pasta?' is the definition.
(I know that Manicotti is a type of pasta)
'wild oregano tip for regular titbit' is the wordplay.
'wild' becomes 'manic' (I've seen this before).
'tip' says to take the initial letters (one tip of the word).
'for' is a charade indicator (letters next to each other).
'regular' indicates alternate letters.
The first letter of 'oregano' is 'o'.
The alternate letters of 'titbit' are 'tti'.
'manic'+'o'+'tti'='MANICOTTI'
'of' is the link.
(Another definition for manicotti that I've seen is " pasta tubes".)
