"A Grammar of the English Tongue" is a notable work by Samuel Johnson, an influential English writer, lexicographer, and critic. This book, published in 1755, was part of Johnson's larger and more comprehensive literary contribution, which also included the famous "A Dictionary of the English Language."

In "A Grammar of the English Tongue," Johnson provides a systematic and detailed examination of the grammar and usage of the English language as it was understood and practiced in the 18th century. The work covers various aspects of grammar, syntax, and linguistic conventions of the time. Johnson's approach to grammar is likely to be prescriptive, offering rules and guidelines for proper usage.

The book reflects Johnson's commitment to language precision and his belief in the importance of maintaining standards in English communication. It was a significant contribution to the study and codification of the English language during a period when there was a growing interest in establishing linguistic norms.
