Limit restricting endless tendency for waffly language (8)
I believe the answer is:
verbiage
'language' is the definition.
(thesaurus)
'limit restricting endless tendency' is the wordplay.
'limit' becomes 'verge' (I can't explain this - if you can you should give a lot more credence to this answer).
'restricting' indicates putting letters inside.
'endless' means to remove the last letter.
'tendency' becomes 'bias' (bias is a kind of tendency).
'bias' with its last letter taken away is 'bia'.
'verge' placed around 'bia' is 'VERBIAGE'.
'for waffly' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for verbiage that I've seen before include "Otiose, meaningless, sentences" , "Prolixity" , "Excessively lengthy speech or writing" , "Excessive number of words to express idea" , "Use of excessive words" .)
