In the early days of printing presses and typeface blocks, letters that would otherwise look strange or take up too much space when placed side-by-side were carved together on the same block. Called ligatures, these interacting letter combinations optimized the rest of the line's spacing and improved the overall readability of the word or the sentence. Adobe InDesign automatically inserts ligatures -- provided the font is designed to support them -- although this setting can be disabled when the feature is unnecessary or unwanted.
