Yes & No! Here again you see some difference between the north and the south. If you are familiar with Southern Chinook Wawa then you will know “wik” (also spelled weyk, weik, or wake) as the general word for “no”. In BC the word for “no” is almost always “heilo” – spelled ilo in Chinuk Pipa, hilu at Grand Ronde and historically spelled halo. Check it out:
*Caveat* – you will commonly see the priests like Le Jeune use the word ‘wik’ as a general word for ‘no’ but this is because they learned from southern speakers. Indigenous speakers in BC very rarely use ‘wik’ to generally mean ‘no’.
For a detailed discussion of these words check out David Robertson’s PhD Dissertation p. 161.
