transitiveness of a verb: whether it can take a direct object or not (“x exists” vs “x causes y”)

rectō and versō foliō are the front and back side of a leaf: in a left-to-right language like this one, recto is the odd-numbered right side of a spread while the verso of the same spread is the left side with the preceding page number.

the obverse=heads of a euro coin is the national side with the dates, the reverse=tails is the common side with the value.

median: the spot where half is above and half below. mode: the most common. arithmetic mean: the sum of n items divided by n. geometric mean: the nth root of the product of n items (for positive items, equal to the antilogarithm of the arithmetic mean of the logarithms of the items). the geometric mean is the only proper mean when averaging normalized figures (such as percentages).
