Does Swahili (and hence cognates of other Bantu languages) simba have any relation to सिंह (~singh or ~simha in Hindi and Sanskrit respectively according to Wiktionary, please correct me if I am wrong), or is it simply a coincidence? After all, they sound very similar and have almost identical meanings. If so, did this borrowing result from contact? Did Bantu and Indic/Indo-European language families have common ancestors? A cursory search on Wikipedia doesn't yield any clues.
