Claiming everything, for example, in front of garage (8)
I believe the answer is:
alleging
'claiming' is the definition.
The answer and definition can be both to do with communicating as well as being present participle verbs.
Perhaps you can see a link between them that I can't see?
'everything for example in front of garage' is the wordplay.
'everything' becomes 'all' (all things).
'for example' becomes 'e.g.' (short for 'exempli gratia', 'for example' in Latin).
'front of' indicates taking the first letters (the letter at the front of the word).
The first letter of 'garage' is 'g'.
'all'+'eg'+'in'+'g'='ALLEGING'
Can you help me to learn more?
(Other definitions for alleging that I've seen before include "Claiming without proof" , "Reporting or maintaining" , "Without legal proof declaring" .)
