Old actors embracing enclosure like mine that lacks depth (8)
I believe the answer is:
opencast
'mine that lacks depth' is the definition.
'opencast' can be an answer for 'mine' (I've seen this before). I am not certain of the remainder of the definition.
'old actors embracing enclosure' is the wordplay.
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'actors' becomes 'cast' (group of actors).
'embracing' indicates putting letters inside.
'enclosure' becomes 'pen' (pen is a kind of enclosure).
'o'+'cast'='ocast'
'ocast' going around 'pen' is 'OPENCAST'.
'like' acts as a link.
Can you help me to learn more?
(Other definitions for opencast that I've seen before include "Method of mining" , "mining - with 6d" , "Sort of mining" , "Surface type of mining" , "sort of mine" .)
