Sanskrit version of Nembutsu

[Nighthawk]

Which is Namo Amitabha Buddha. Can it also be said as "Namo Amita Buddha?"

[Aemilius]

I have been taught it in the form Namo Amitabhaya, and as Namo Amitabha Buddhaya.
In the Dharani for Rebirth ( in Sukhavati) it is Namo Amitabhaya Tathagataya, http://www.sutrasmantras.info/mantra05.html
The ending ya means 'for' or 'to', as in Salutation to Amitabha.
