Yes, all African languages that I know have many metaphors and simile's compared to a proto-English (discounting English loaning from other languages) and these have intrinsic knowledge built into them. For example, in Nortern Sotho: "Ditau ga di adimane meno." This means that "Lion don't lend each other their teeth." But in context it means that you can't expect that other people lend you tools when you have to do a job, everyone needs to bring their own tools (physical or otherwise; software or hardware; etc). I also suspect that this saying alludes to the fact that lions are in competition with each other. Why would a lion lend another lion it's teeth and in the process put itself at a disadvantage? The metaphor encodes this inherent truth about competition.
