Antiparticle with no resistance outside current location (8)
I believe the answer is:
position
'current location' is the definition.
'position' can be an answer for 'location' (synonyms). I am not sure about the 'current' bit.
'antiparticle with no resistance outside' is the wordplay.
'antiparticle with' becomes 'po' (I can't explain this - if you can you should believe this answer much more).
'no' becomes 'O' (O resembles 0).
'resistance' becomes 'sit-in' (sit-in is a kind of resistance).
'outside' is an insertion indicator (some letters go outside others).
'o' put into 'sitin' is 'sition'.
'po'+'sition'='POSITION'
Can you help me to learn more?
(Other definitions for position that I've seen before include "Job; point of view" , "Place where something is" , "Office - location" , "Location or attitude" , "case" .)
