This Aish article about the meaning of the word "Adam" states the following:
The letter aleph is also a word which means to teach or inculcate. It similarly indicates leadership, as implied by the related word aluf which means a general or tribal head.
A quick search of translate.google.com did not verify this statement. Neither does the Collins English Dictionary, though it did (suprisingly, as it's an English dictionary) verified that the word origin suggests leadership based on the word aluf.
Is the source correct? Is the letter Aleph (א) also a word that means "to teach, inculcate"?
