What is the ‘coimas’ of the Eldar?

mana

what is

mana interogative, a word translated "what is" in the sentence mana i-coimas Eldaron[?] "what is the coimas (lembas) of the Eldar?" (PM:395, a variant reading in PM:403) Either this is *ma "what" + "is", or mana may itself be a unitary word "what", and there is not really any word meaning "is" in the sentence. Since ma is assigned other meanings elsewhere, the latter interpretation may be the more likely.
