Still one phone after meeting starts (8)
I believe the answer is:
immobile
'still' is the definition.
(thesaurus)
'one phone after meeting starts' is the wordplay.
'one' becomes 'i' (Roman numeral).
'phone' becomes 'mobile' (I've seen this before**).
'after' says to put letters next to each other.
'starts' suggests taking the first letters.
The first letter of 'meeting' is 'm'.
'mobile' put after 'm' is 'mmobile'.
'i'+'mmobile'='IMMOBILE'
(Other definitions for immobile that I've seen before include "rooted" , "Incapable of motion" , "Not going anywhere" , "Unable to move" , "Static" .)
