The latest inventory appears in the work of Yeda Pessoa de Castro (2001), who lists 3,517 terms of African origin found during a survey carried out in Bahia, which can generally be extended to Brazilian Portuguese as a whole. Most of these terms refer to the world of religion, followed by words related to food, music, dance, etc. This is a specialized lexicon, often of regional use. The vocabulary effectively employed in a general sense is less extensive, as found by Alkmim and Petter (2008) in a survey of words of African origin commonly used in Brazil today and belonging to the mainstream vocabulary (i.e. nonspecialized use only). This analysis led them to identify 56 words common to the world of the respondents. The authors separated the terms into three categories:  
Category 1, which includes words that can be used in any kind of social interaction (30 words): abada, banzo, caçamba, cachaça, cachimbo, caçula, candango, canga, capanga, carimbo, caxumba, cochilar, corcunda, dengo, fubá, gibi, macaco, maconha, macumba, marimbondo, miçanga, molambo, moleque, moringa, quilombo, quitanda, quitute, senzala, tanga, xingar;  
Category 2, consisting of informal terms used colloquially that, depending on the situation, can be replaced by others ( 9 words): bamba/bambambã, banguela, cafuné, catimba, catimbeiro, catinga, mandinga, muamba, muxoxo;  
Category 3, listing markedly informal words of restricted use (17 words): angu ("confusion"), babaca, babau, biboca, bunda, cafofo, cafundó, cambada, cucuia, muquifo, muquirana, muvuca, muxiba, quizumba, sacana, ziquizira, zumbi.
