Will it give a ghostly light? (6,4)
I believe the answer is:
spirit lamp
'light?' is the definition.
(spirit lamp is a kind of light)
'will it give a ghostly' is the wordplay.
I cannot quite understand how this works, but
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is located in the answer.
'a' could be 'amp' (A is the symbol for the amp or ampere) and 'amp' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for spirit lamp that I've seen before include "this'll lighten things up" , "Meths-burning light" .)
