Like dripping taps, odd bits cast in silver (6)
I believe the answer is:
greasy
'like dripping taps odd bits' is the definition.
I can't tell whether this defines the answer.
'cast in silver' is the wordplay.
'cast' becomes 'as' (I can't explain this - if you can you should believe this answer much more).
'in' indicates putting letters inside.
'silver' becomes 'grey' (similar in meaning).
'as' placed into 'grey' is 'GREASY'.
Can you help me to learn more?
(Other definitions for greasy that I've seen before include "Thickly oleaginous" , "Sticky with fat" , "Oily or smeared with fat" , "Like the pole that is hard to climb" , "'Fatty, oily (6)'" .)
