Ghastly look of some municipal lorries (6)
I believe the answer is:
pallor
'ghastly look' is the definition.
The definition and answer can be both human attributes as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'some municipal lorries' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'PALLOR' can be found hidden inside 'municipal lorries'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for pallor that I've seen before include "Paleness of complexion" , "Unnatural whiteness" , "Paleness of face" , "Paleness as from illness" , "Unnatural lack of colour in the skin" .)
