Projecting part of a Times New Roman letter (5)

I believe the answer is:

serif

(Other definitions for serif that I've seen before include "Projection on a letter in some fonts" , "stroke of the pen" , "Short line at the end of the main strokes of a printed character" , "Small line used in printing type" , "addition to character?" .)

I've seen this clue in The Wall Street Journal.
