A preposition is a word that expresses a relationship between one noun or noun phrase and another word or element in the same sentence:

Trans la fluvio e tra la bosko, che Avino ni iras. Over the river and through the woods, to Grandmother’s house we go.
Violinagar dum ke Roma brulas To fiddle while Rome burns
Ne kun foxo. Ne en buxo. Nek en domo o kun muso. Not in a box. Not with a fox. Not in a house. Not with a mouse.

In Ido, prepositions never end a sentence, as they often do in English:

Pro quo vu facis to? What did you do that for?
Pri quo esas ca filmo? What is this movie about?

There is also an “anything” preposition in Ido, ye, which has no definite meaning of its own but is used when no other preposition seems appropriate. It is often used to translate “at” with reference to time or place.

ye la lasta foyo the last time (something happened)
il prenis el ye la manuo he took her by the hand
ye dimezo at noon
