Watering place in cyberspace? (3)
I believe the answer is:
spa
'watering place' is the definition.
(synonyms)
'in cyberspace?' is the wordplay.
'in' indicates a hidden word.
'SPA' is hidden in the letters of 'cyberspace'.
(Other definitions for spa that I've seen before include "Health resort at a mineral spring" , "Hydromassage facility" , "town for his health!" , "Watering place" , "eg Vichy" .)
