Given an arrow head symbol, formed by two lines, is there a name for each of  these lines, individually?  If not, perhaps a term that could be used to clearly convey that idea?  For example: "arrowhead edge"?

If I had to choose among flavors, I would prefer a term that would be understood in American English.

Note: I'm getting answers and comments describing an arrow head.  I don't want that.  I want to know the name of a line that makes up half of an arrow head.

  • You want its definition in British English or American English? – user121863 Feb 22 '18 at 19:22
  • @user5768790 American would be nice... though are the different? – Jonathan Mee Feb 22 '18 at 19:28

    We say side of a square. There is no word that makes a side distinctly belong to a square. I would say edge of an arrow. – jxh Feb 22 '18 at 20:15

    I’d be inclined to use ‘‘leg’’, but I don’t know whether I’ve ever heard that usage. – Scott Feb 22 '18 at 20:18

Though not typically used in relation to symbology, in hunting this would commonly be referred to as a "barb":

A point or pointed part projecting backward from a main point, as of a fishhook or arrowhead

vertical:the right/left arm of arrowhead? horizontal:lower/upper arm?

The R package ggplot2 uses the term "arrow head" and that makes sense to me too in ordinary BrE.

  • Ummm... it makes sense that one of the lines which forms an arrow head is called the arrow head? – Jonathan Mee Feb 22 '18 at 19:51

    Well, it makes almost as much sense as the fact that a ‘‘day’’ is divided into two parts, one of which is ‘‘day’’. – Scott Feb 22 '18 at 20:09
  • @Scott You make a fair point but if I was trying to differentiate I'd probably say something like daytime and nighttime. Similarly I want a way to differentiate the edges of an arrowhead from the collective arrowhead. – Jonathan Mee Feb 22 '18 at 20:14

    So, you wouldn’t refer to the summer solstice and the winter solstice as “the longest day of the year” and “the shortest day of the year”?    :-)    ⁠ – Scott Feb 22 '18 at 20:25
