Excavate almost everything with the fingers (7)
I believe the answer is:
digital
'with the fingers' is the definition.
(I've seen this before)
'excavate almost everything' is the wordplay.
'excavate' becomes 'digit' (I can't explain this - if you can you should give a lot more credence to this answer).
'almost' means to remove the last letter (most of the word but not all of it).
'everything' becomes 'all' (all things).
'all' with its final letter taken away is 'al'.
'digit'+'al'='DIGITAL'
Can you help me to learn more?
(Other definitions for digital that I've seen before include "As most computers" , "Works with through numerals, like watch" , "Like computer technology" , "Replacement for analogue" , "Opposite of analogue" .)
