Announced plan: lead-free gear like theirs, say (6,7)
I believe the answer is:
tongue-twister
'say' is the definition.
(I know that tongue-twister is a type of say)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for tongue-twister that I've seen before include ""Red lorry, yellow lorry", for example" , ""I wish to wash my Irish wristwatch", perhaps" , "Peter Piper picked a peck of pickled pepper, for instance" , "Phrase that is difficult to say properly" , "Sequence of words difficult to say" .)
