"What do you think, Shariputra, for what reason is that Thus Come One called 'Limitless Light'?" Shakyamuni Buddha has been telling his disciple why Amita Buddha is called Amitayus "Limitless Life," and now he asks about his other name saying: tat-kim "what" manyase "do you think" sariputra "Shariputra," kena "for what" karanena "reason" (is) sa "that" tathagato "Thus Come One" namocyate "(is) called" (a)mitabho (Amitabha) "Limitless Light. Consult previous Sanskrit lessons for a full discussion of the vocabulary and grammar. Note how the sounds combined in this: sa tathagato'mitabho namocyate. sas became sa before initial t-. tathagatas + amitabhas became tathagato'mitabho (the combination of final -as and initial a- resulting in nothing being left but -o; and the final -as before initial n- also turning to -o). Note that the Sanskrit for "Namo Amitabha Buddha" with the sound changes and case ending for the dative is: namo'mitabhabuddhaya. The question now is why is that Buddha called Amitabha, "Limitless Light"?
