Two or more letters are joined together to form one glyph or character.
Definition: Two or more letters combined into one character make a ligature. In typography some ligatures represent specific sounds or words such as the AE or æ diphthong ligature. Other ligatures are primarily to make type more attractive on the page such as the fl and fi ligatures. In most cases, a ligature is only available in extended characters sets or special expert sets of fonts.
Ligatures used to improve the appearance of type are usually character pairs or triplets that have features that tend to overlap when used together. The ligature creates a smoother transition or connection between characters by connecting crossbars, removing dots over the i, or otherwise altering the shape of the characters.
In writing and typography, a ligature occurs where two or more graphemes are joined as a single glyph. Ligatures usually replace consecutive characters sharing common components and are part of a more general class of glyphs called “contextual forms” where the specific shape of a letter depends on context such as surrounding letters or proximity to the end of a line.
A printed or written character (as æ or ƒƒ) consisting of two or more letters or characters joined together.
