Turn it on

Kern­ing is the adjust­ment of spe­cific pairs of let­ters to improve spac­ing and fit. (It dif­fers from letterspacing, which affects all pairs.) Most fonts come with hun­dreds and some­times thou­sands of kern­ing pairs inserted by the font designer.

Below, notice how kern­ing reduces the large gaps between cer­tain let­ter pairs, mak­ing them con­sis­tent with the rest of the font.

Always use kern­ing. By default, kern­ing is not acti­vated in Word or Word­Per­fect, so you have to turn it on your­self. If you use paragraph and character styles, turn on kern­ing as part of your style def­i­n­i­tions.
