Some cultural elements are more resilient to language change, namely, religion and folklore. Salishan language communities that have demonstrated change in technology and environmental vocabulary have often remained more consistent with their religious terminology. Religion and heavily ingrained cultural traditions are often regarded as sacred, and so are less likely to undergo any sort of change. Indeed, cognate lists between various Salishan languages show more similarities in religious terminology than they do in technology and environment vocabulary. Other categories with noticeable similarities include words for body parts, colors, and numbers. There would be little need to change such vocabulary, so it's more likely to remain the same despite other changes between languages. The Coast Salishan languages are less similar to each other than are the Interior Salishan languages, probably because the Coast communities have more access to outside influences.
