Besides case, the role of a noun in a clause may be indicated with an adposition. This may occur either as a preposition before the noun, as in English, or as an suffix at the end of the noun, as in Japanese, a greater degree of freedom than human languages allow. For example, "with you" may be either hu nga or ngahu. When used as suffixes, they are much like the numerous cases found in Hungarian and Finnish.

Attested adpositions


Adpositions may be stressed when they occur as prepositions, but not as suffixes, where they have no effect on the stress of the noun.

Various locative and temporal adverbs are derived from these: neʼìm "toward the back", nefä "upwards", nekll "downwards"; taʼem "from above";[note 3] mawkrr "after, afterwards"; srekrr "before, beforehand". Note also kä neto "go away (toward the distance)" and tok mìso "be there in the distance", both perhaps based on the particle to "than". Sreseʼa "to prophesize" is literally "to foresee", sre+tseʼa.

There are words besides traditional adpositions that have the same dual preposition/suffix use, such as "and" and pe+, -pe "which?", though the latter case is a dual prefix/suffix (peu, ʼupe "what?"—see Questions), never a preposition.

Though a prefix, the adverbial nì- "-ly" functions as a generic adposition: fyaʼo alaw "in a clear manner". It may be used where no specific adposition is correct; mì fyaʼo, for example, would mean literally "in the way, on the path", not *"in the manner".

Lenition and the ambiguity of short plurals


When used as prepositions, certain of these trigger lenition, marked "+" in the table above. One of the leniting prepositions is "in", as in mì sokx "in the body", from tokx "the body". This may cause some ambiguity with short plurals: mì sokx could also be short for mì aysokx "in the bodies". When is used as a suffix, however, the noun is not lenited.

noun preposition + noun noun-suffix
Singular tokx "body" mì sokx "in the body" tokxmì "in the body"
Short plural sokx "bodies" "in the bodies" sokxmì "in the bodies"
Long plural aysokx mì aysokx aysokxmì


  1. Kxamlä does not cause lenition, though its component ilä does.
  2. Syntactically, is a conjunction, and is used regardless of the presence of true adpositions or case, but it is included here because it may be either preposed or suffixed as the adpositions are.
  3. Perhaps related to the em in emzaʼu "to pass a test, overcome a challenge".
