Theatrical educationist, one put up in tent? (4,3)
I believe the answer is:
camp bed
'one put up in tent?' is the definition.
(bed put up in a tent)
'theatrical educationist' is the wordplay.
'theatrical' becomes 'camp' (I've seen this before).
'educationist' becomes 'bed' (someone with a Bachelor of Education degree).
'camp'+'bed'='CAMP-BED'
(Other definitions for camp bed that I've seen before include "Portable bunk" , "Folding support for sleeper" , "Structure on which to sleep in a tent" , "temporary overnight accommodation" , "outdoor resting place?" .)
