Many ligatures combine f with the following letter. A particularly 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. Other ligatures with the letter f include fj, fl (ﬂ), ff (ﬀ), ffi (ﬃ), and ffl (ﬄ). Ligatures for fa, fe, fo, fr, fs, ft, fb, fh, fu, fy, and for f followed by a full stop, comma, or hyphen are also used, as well as the equivalent set for the doubled ff.
