Definition

A bigram is a sequence of two adjacent elements from a string of text. These elements can be letters, syllables, or words, depending on the level of analysis. In simple terms, it's a pair of consecutive things that appear together. 👯 Bigrams are used in various fields like linguistics, natural language processing, and cryptography to analyze patterns and frequencies. For example, in the sentence "The cat sat," the bigrams would be "The cat", "cat sat." They provide insights into the structure and probability of sequences within a text.

Etymology

The word 'bigram' is a combination of 'bi-' meaning two, and '-gram' meaning something written or recorded. 'Bi-' comes from the Latin 'bis,' meaning twice. '-gram' derives from the Greek 'gramma,' meaning a letter or something written. The term reflects the concept of a two-element sequence, specifically in written or linguistic contexts. The use of bigrams dates back to early statistical analysis of texts.
