Not recalling names, confused, I start to ad-lib (7)
'not recalling' is the definition.
(amnesia affects someone's memory)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for amnesia that I've seen before include "As a mine (anag)" , "Seaman I found in state of memory loss" , "Memory-loss" , "Partial or total loss of memory" , "Inability to recall" .)
'not recalling names confused' is the definition.
I can't tell whether this definition defines the answer.
'i start to ad-lib' is the wordplay.
I cannot really see how this works, but
'i' could be 'me' and 'me' is located in the answer.
This explanation may well be incorrect...
