Kerning is the distance between letters. Some letters take up more space than others, although the same space is allocated to all. When the space between the letters is adjusted, then we say we have applied kerning.
|Kerning has been applied to the second sentence.||The picture below has a guideline, which makes the kerning clearer|
The first sentence has no kerning. The e's appear to be spaced out a bit. In the second sentence, the e's have been kerned, so they are closer to the previous letter. The word 'the' was particularly in need. The amount of kerning required depends on the typeface, and the size of the words. Headings often need some kerning.
