Repressed memory restricting limits of acting star (9)
I believe the answer is:
pentagram
'star' is the definition.
(pentagram is a kind of star)
'repressed memory restricting limits of acting' is the wordplay.
'repressed' becomes 'pent' (I can't justify this - if you can you should give a lot more credence to this answer).
'memory' becomes 'ram' (RAM is an example).
'restricting' indicates putting letters inside.
'limits of' says to hollow out the word (remove centre letters).
'acting' with its middle removed is 'ag'.
'pent'+'ram'='pentram'
'pentram' enclosing 'ag' is 'PENTAGRAM'.
Can you help me to learn more?
(Other definitions for pentagram that I've seen before include "Five-pointed star" , "Five pointed star" , "Star-shaped figure" , "Mystical symbol" , "magical symbol" .)
