Either way it's a light touch (3)
I believe the answer is:
tap
'light touch' is the definition.
(I've seen this in another clue)
'either way it's a' is the wordplay.
I cannot quite see how this works, but
'a' is within the answer.
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is located in the answer.
A single letter 'p' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for tap that I've seen before include "Water source; take advantage of" , "Water controller" , "Light touch (hot or cold?)" , "A form of dance" , "water supply" .)
