Pāli amha (amhan)
In the Pali-English Dictionary, Davids and Stede say that the Pali words amha (amhan)refer to “a stone.” It also has a cognate form, aśman in Sanskrit, with the same meaning, “a stone.” It is an offshoot of Tamil akku through the transformation of akku > aṡ > áṡman > amha (amhan). The following words, related to Pali amha and amhan, also trace their origin to Tamil akku
amha-maya and amhan-maya, “made of stone, hard.”
