Wrecked, having carried round the entire load (8)
I believe the answer is:
totalled
'wrecked' is the definition.
(I've seen this in another clue)
'carried round the entire load' is the wordplay.
'carried round' becomes 'toted' (toting is a kind of carrying. I am not sure about the 'round' bit.).
'the entire' becomes 'all' (I've seen this before).
'load' means one lot of letters goes inside another (some letters are loaded into others).
'toted' placed around 'all' is 'TOTALLED'.
'having' acts as a link.
Can you help me to learn more?
(Other definitions for totalled that I've seen before include "Summed" , "completely destroyed" , "came to" , "Determined the sum of" , "blown away" .)
