–veru, suf. Vector suffix; not to be confused with the noun súveru. Usually used with a natural number prefix, e.g. lenveru for a two-dimensional vector. However, natural numbers are not the only acceptable prefix; to describe a matrix, hé can be inserted; e.g. lenhélenveru for a 2×2 matrix. As a back-formation from this, a two-dimensional matrix of arbitrary size is called a héveru.
