bigram
Two-character text unit
A bigram is a sequence of two adjacent elements, typically letters or words, analyzed as a unit.
In computational linguistics, bigrams help predict what word might follow another: the bigram "New York" appears frequently in American text.
Letter bigrams like "th" or "qu" reveal patterns in spelling and language structure.
