In this place at present, yet in no place at all (7)
I believe the answer is:
nowhere
'in this place at present yet in no place at all' is the definition.
'nowhere' can be an answer for 'place' (I have seen 'Nonexistent place' mean 'nowhere' so perhaps 'place' could also mean 'nowhere'). I'm not certain of the rest of the definition.
'in this place at present' is the wordplay.
'in this place' becomes 'here' (synonyms).
'at' means one lot of letters go next to another (I've seen this in other clues).
'present' becomes 'now' (both can mean the current period).
'here' after 'now' is 'NOWHERE'.
Can you help me to learn more?
(Other definitions for nowhere that I've seen before include "... and the rest ____"" , "In no particular place" , "Neither here nor there?" , "remote location" , "It can't be found!" .)
