Tiu

Esperanto

Esperanto ti- (demonstrative correlative prefix) + -u (correlative suffix of individuals)

tiu (plural tiuj, accusative singular tiun, accusative plural tiujn)

that [one/person] (demonstrative correlative of individuals)
As with other demonstrative correlatives in Esperanto, tiu can be combined with ĉi, the adverbial particle of proximity, or with for, the adverbial particle of distance. Tiu ĉi thus means this [here] [one/person] and tiu for means that [distant] [one/person].fr:tiu
