No great surprise that squaw, one of the few supposedly Native American terms that my generation absorbed in our youth through the insidious influence of TV, is now widely considered “offensive, derogatory, misogynist, and racist”, as an interesting wiki article observes.
In English the word was first used in colonial literature in 1622. An article in Indian Country Today makes a token attempt at balance (“squaw is either offensive or historically accurate in portraying a female Indian woman”; see also here); but even if linguists are correct to query the connection of the S-word with the C-word, there are plenty of reasons to reject the term.
And the experimental Native American singer Jim Pepper included Squaw song on his 1971 album Pepper’s Pow Wow. But by then squaw was among a whole range of stereotypes that were being discredited. For such images in well-meaning early documentaries, see my post on Navajo culture, under “On film”; see also Native American cultures: a roundup.
In November 2021, in line with decades of work by Indigenous activists, Secretary of the Interior Deb Haaland furthered the movement to remove offensive place-names.
