Etymology

Esperanto ti- + -o (correlative suffix of objects)

Pronoun

tio (plural tioj, accusative singular tion, accusative plural tiojn)

1. that [thing] (demonstrative correlative of objects)

Usage notes

As with other correlatives of objects, and unlike English that, tio always functions as a noun, never an adjective. As with other demonstrative correlatives in Esperanto, tio can be combined with ĉi, the adverbial particle of proximity, or with for, the adverbial particle of distance. Tio ĉi thus means this [here] [thing] and tio for means that [distant] [thing].
