x1 is (n) more than x2 in metric x3 [ni, default cardinality]
I.e. |x2| + n = |x1| where x3 determines how to measure |x|. Practically, this can be used, e.g. «djica tu'a le pa zau'ei be lei titla» for "I want one more candy". See also: mei'ai, ze'au, ja'au Etymology: za'u+mei (note that za'u ny. mei means something different).
