kerning
Kerning controls the spacing between two characters. Typical examples of combination that require subtle kerning are an r following a T (the “r” has to nestle underneath the right-hand bar slightly) or an LY pair that have to nudge closer together. You can control kerning manually, or you can turn on the kerning built into a font by the font designer.
kerning pairs
In typesetting, certain pairs of letters, by nature of their design, require kerning to improve their typeset appearance. Most digital typefaces have a series of predefined kerning pairs, such as A and W. The system user can make adjustments to the preset amount of space for a specific kerning pair.
