A hundred and fifty putting on facing for building (8)
I believe the answer is:
cladding
'building' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'a hundred and fifty putting on facing' is the wordplay.
'a hundred' becomes 'C' (Roman numerals).
'and' is a charade indicator (letters next to each other).
'fifty' becomes 'L' (Roman numeral).
'putting on' becomes 'adding' (I've seen this in another clue).
'facing' means one lot of letters go next to another.
'c'+'l'+'adding'='CLADDING'
'for' is the link.
Can you help me to learn more?
(Other definitions for cladding that I've seen before include "protective coat" , "protective material" , "Outside wall covering" , "Exterior covering" , "insulating layer" .)
