Insincere tribute and terrible spiel on right to have a bad habit (3,7)
I believe the answer is:
lip service
'insincere tribute' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'terrible spiel on right to have a bad habit' is the wordplay.
'terrible' is an anagram indicator.
'on' means one lot of letters go next to another.
'right' becomes 'r' (common abbreviation).
'to have' means one lot of letters go next to another.
'a bad habit' becomes 'vice' (a sin or weakness).
'spiel' anagrammed gives 'lipse'.
'lipse'+'r'+'vice'='LIP-SERVICE'
'and' acts as a link.
Can you help me to learn more?
(Other definitions for lip service that I've seen before include "Insincere offer to assist" , "Insincere praise" , "The hypocrisy" , "Insincere support" , "It may be paid" .)
