Bluth upset with main form of digital protection? (9)
I believe the answer is:
thumbnail
'form of digital protection?' is the definition.
The answer and definition can be both body parts as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'bluth upset with main' is the wordplay.
'upset with' indicates anagramming the letters.
'bluth' mixed up with 'main' makes 'THUMBNAIL'.
Can you help me to learn more?
(Other definitions for thumbnail that I've seen before include "Sort of sketch" , "This sketch is short and concise like manual appendage" , "type of sketch" , "Particular sketch" , "small picture" .)
