End part of a letter (5)
I believe the answer is:
serif
'part of a letter' is the definition.
(I've seen this in another clue)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for serif that I've seen before include "stroke of the pen" , "Feature of some typefaces" , "One feature of text" , "Typeface decoration" , "Style of type-face" .)
