Engage in a conversation with a father at the end of a line perhaps? (8)
I believe the answer is:
approach
'engage' is the definition.
(thesaurus)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for approach that I've seen before include "Come near - means of access" , "Move towards" , "attitude" , "golf shot" , "Resemble" .)
