That makes sense. From my perspective, having worked in Brazil (and having been a student of the Portuguese language) for some years, I've come to understand there's actually a strong pride in the Portuguese language in Brazil and in being distinct from the Spanish-speaking countries around it, and this has resulted in Spanish being a tiny minority language in Brazil. The other contributing factor I think is that most Brazilians have little reason to actually learn Spanish because the languages are similar enough to enable simple interactions (at least on the surface -- they diverge significantly upon diving deeper). As a result, the presence of Spanish in Brazil is actually very small. Hence my original comment that it would be very unusual for Pirahã words to have the possibility of Spanish as an influence. The French situation in Canada is a little different (speaking as a former Quebec resident). French is a co-official language in Canada spoken as an L1 by 20% of the population (and L1 speakers aren't only in Quebec, but also Alberta, Manitoba, Ontario and New Brunswick). Also, internationalizing for French isn't just a good idea, it is the law. Retailers in the U.S. know that consumer products without French labeling cannot be sold commercially in Canada.
