We all gram for n-grams

An n-gram is a sequence containing up to n elements that have been extracted from a sequence of those elements, usually a string. In general the “elements” of an n-gram can be characters, syllables, words, or even symbols like “A,” “T,” “G,” and “C” used to represent a DNA sequence.^[6]
