akác (mmea wa majani makali)

I'm sorry, but "akác (mmea wa majani makali)" does not appear to be a standard Spanish word or phrase. It seems to include a mix of languages, possibly Swahili, given the phrase "mmea wa majani makali," which translates to "plant with sharp leaves." If you meant a specific word or phrase in Spanish, please provide it, and I will be happy to assist with its definition. tuntematon
