Built with steeply angled sides, A&E accommodates female sheep (1-5)
I believe the answer is:
a-frame
'built with steeply angled sides ae accommodates female sheep' is the definition.
I can't tell whether this defines the answer.
'ae accommodates female sheep' is the wordplay.
'accommodates' is an insertion indicator.
'female' becomes 'f' (abbreviation).
'sheep' becomes 'ram' (male sheep).
'f'+'ram'='fram'
'ae' placed around 'fram' is 'A-FRAME'.
Can you help me to learn more?
(Other definitions for a-frame that I've seen before include "Common house roof structure" , "Timber structure used in building" .)
