Art of Grammar of the Most Used Language on the Coast of Brazil

Art of Grammar of the Most Used Language on the Coast of Brazil (Portuguese: Arte de gramática da língua mais usada na costa do Brasil) is a book written in 1555 by Jesuit priest Joseph of Anchieta and first published in Portugal in the year 1595. It is the first grammar of a Brazilian Indigenous language—in this case, Old Tupi—and the second one of an American Indigenous language, following the grammar of Quechua by Domingo de Santo Tomás, published in 1560.
