Note 9 — PART I

It must be remembered that all roots or root-words in Esperanto are either sexless, or have only the sex naturally belonging to the root, unless the feminine suffix—IN—be added. For instance, vir- gives the idea of "man" (male), therefore viro = a man; and we always speak of viro as li = he, because we are sure the noun refers to the male sex. But the root infan- gives only the idea of a "child" (neuter), so, unless we actually know the child is a male, we speak of infano = child as ĝi = it, just as we do in English. When a suffix denoting a person, such as -estr-, -ist-, -ul-, is added to a root, the noun is sexless, or may be presumed to be masculine, unless the feminine -in- be also added.
