Get involved, teen cried out (9)
I believe the answer is:
intercede
'get involved' is the definition.
Although both the answer and definition are verbs in their base form, I don't understand how they can define each other.
'teen cried out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'teen'+'cried'='teencried'
'teencried' is an anagram of 'INTERCEDE'.
Can you help me to learn more?
(Other definitions for intercede that I've seen before include "plead in prayer" , "Act between parties to reconcile differences" , "Intervene, on behalf of another" , "Plead for someone" , "Come between as mediator" .)
