Like an esoteric cry by the wild Pict (7)
I believe the answer is:
cryptic
'like an esoteric' is the definition.
I can't tell whether this definition defines the answer.
'cry by the wild pict' is the wordplay.
'by' means one lot of letters go next to another.
'the wild' is an anagram indicator.
'pict' anagrammed gives 'ptic'.
'cry'+'ptic'='CRYPTIC'
Can you help me to learn more?
(Other definitions for cryptic that I've seen before include "Like some crosswords" , "Esoteric" , "Obscure or puzzling (as our neighbour Crossheir)" , "Like our other puzzle" , "The other kind of crossword" .)
