Like a buccaneer, possibly impractical but not calm (7)
I believe the answer is:
piratic
'like a buccaneer' is the definition.
I can't judge whether this definition defines the answer.
'possibly impractical but not calm' is the wordplay.
'possibly' indicates an anagram.
'but not' indicates named letters should be taken away.
'impractical' with 'calm' taken away is 'iprtica'.
'iprtica' anagrammed gives 'PIRATIC'.
Can you help me to learn more?
(Other definitions for piratic that I've seen before include "just like 25 [HOOK] ?" , "of privateer" , "such as Blackbeard?" .)
