Chapter by English poet is easy to understand (5)
I believe the answer is:
clear
'easy to understand' is the definition.
(I've seen this in another clue)
'chapter by english poet' is the wordplay.
'chapter' becomes 'c' (abbreviation).
'by' is a charade indicator (letters next to each other).
'english poet' becomes 'lear' (poet Edward Lear. I am not sure about the 'english' bit.).
'c'+'lear'='CLEAR'
'is' is the link.
Can you help me to learn more?
(Other definitions for clear that I've seen before include "Open; not cloudy" , "Not obstructed" , "Unobstructed" , "Patent" , "Bright" .)
