Congested; cramped (7)
I believe the answer is:
crowded
I believe this is a double definition.
'congested' is the first definition.
(thesaurus)
'cramped' is the second definition.
(I've seen this before)
(Other definitions for crowded that I've seen before include "cramped" , "With too many people" , "Thronged, overfilled" , "Jam-packed" , "Packed (of people)" .)
