Why some fonts have the 'f' and 'i' joined


I noticed today that when I type a word with the character pair fi in it, the f changes when the i is typed to have a longer top and the dot above the i is removed.

I was wondering if this occurrence has a name and, additionally, do fonts that support this functionality have a categorical name?

Accepted Answer

This is called ligature.

In writing and typography, a ligature occurs where two or more graphemes or letters are joined as a single glyph.

Many ligatures combine f with an adjacent letter. The most prominent example is fi (or f‌i, rendered with two normal letters). The tittle of the i in many typefaces collides with the hood of the f when placed beside each other in a word, and are combined into a single glyph with the tittle absorbed into the f.

fi as example for ligatures
