Boring scripture-packed commercial (4)
I believe the answer is:
arid
'boring' is the definition.
(thesaurus)
'scripture-packed commercial' is the wordplay.
I cannot quite understand how this works, but
'scripture' could be 'ri' (I've seen this in other clues) and 'ri' is present in the answer.
'commercial' could be 'ad' and 'ad' is found within the remaining letters.
No letters remain.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for arid that I've seen before include "Lacking sufficient rainfall" , "Dry, devoid of interest" , "flat" , "Parched with heat" , "Excessively dry" .)
