Transported cases fully made (8)
I believe the answer is:
totalled
'made' is the definition.
The definition and answer can be both to do with communicating as well as being past participle verbs.
Perhaps they are linked in a way I don't understand?
'transported cases fully' is the wordplay.
'transported' becomes 'toted' (toting is a kind of transporting).
'cases' means one lot of letters goes inside another (forms a case around).
'fully' becomes 'all' (I've seen this in another clue).
'toted' placed around 'all' is 'TOTALLED'.
Can you help me to learn more?
(Other definitions for totalled that I've seen before include "Summed" , "completely destroyed" , "Determined the sum of" , "Added together" , "blown away" .)
