Language Log was started on July 28, 2003, by Liberman and Pullum, a linguist then at the University of California, Santa Cruz (now at the University of Edinburgh). One early post about a woman who wrote egg corns instead of acorns led to the coinage of the word eggcorn to refer to a type of sporadic or idiosyncratic re-analysis. Another post about commonly recycled phrases in newspaper articles, e.g. "If Eskimos have N words for snow, X surely have Y words for Z", resulted in the coinage of the word snowclone. Both phenomena are common topics at the blog, as is linguification, or the use of metaphors that turn factual observations into claims about language in general (many of which are false).

The blog has a number of recurring themes, including the difficulty of transcribing spoken utterances accurately, misuse or misunderstanding of linguistic science in the media, criticism of the popular style guide The Elements of Style by E. B. White and William Strunk Jr., and complaints about what the contributors see as the pedantry of ill-informed prescriptivists, including that of some copyeditors (one of the blog's tags is "prescriptivist poppycock").^[4] In addition, the site has critically addressed opinions and theories related to the Sapir–Whorf hypothesis concerning the relationship between culture, thought and language. Another common topic on the blog is the handling of taboo language in the media. Regular contributor Arnold Zwicky wrote a series of posts describing which words are considered obscene in various publications, paying particularly close attention to the way these words are "asterisked" in the different media forms.

The Becky Award is a tongue-in-cheek award given out by the site. It is named after the sixteenth-century humanist Johannes Goropius Becanus, who claimed to have proved that the language of Eden was Dutch (his mother tongue).

The award for 2006 went to Louann Brizendine for her bestselling book, The Female Brain, which makes two principal claims: that women use language very differently from men, and that the causes of these differences are hormonal. Language Log's contributors quoted Nature ("riddled with scientific errors"), tracked down references in little-known journals, and presented counterarguments using the same referenced sources that Brizendine's claims drew from to demonstrate their lack of scientific reliability.^[5][6][7]
