In Celinese, prepositions can be inflected for person and number - thus, "to me", "for him", and "with you" are translated using single words: moir, dothys, cêith. Most follow a regular pattern for all the singular persons and the 1st person plural (-om, -oth, -os, -wyr), with you plural (-ot, -not) and they (-not, -syr, -sot) being more unpredictable.
Some adpositions have a completely unexpected inflection system. Here are twenty-five of the most common adpositions, inflected for all persons. Note that words composed of two or more component adpositions tend to be inflected like the last root: e.g. golaith (away from) is inflected as laith (toward)
