Postpositions without complements generally derive from postpositions with complements, not from prepositions. Hence, although the postposition ôf from does not appear as preposition, it does appear as an intransitive postposition, as in ôfprate agree, and it may also appear as a postposition with an Adposition Phrase (PP) complement, as illustrated in the example below:

Some adpositions have two forms, depending on whether they appear as a preposition or as a postposition. So the preposition oant until appears in postpositional form as oan (ta). However, the form oant never appears as a bare postposition. This provides an argument that intransitive postpositions do not derive from prepositions but from transitive postpositions. Similar arguments can be constructed on the basis of data from Dutch.

There are also bare adpositions which are not homophonous to prepositions or postpositions. A case in point is the bare adposition fuort away. This can be used as an adposition with an external argument, as shown below:

Fuort does not take PP complements:

The adposition fuort has a transitive counterpart, which is wei away. As the example in (3) indicates, the latter adposition accommodates a PP complement. Although, fuort does not take any complement, it may be modified:

To sum up, the class of intransitive adpositions shows a greater overlap with the class of postpositions than with the class of prepositions. However, there are intransitive adpositions which are homophonous to neither prepositions nor to postpositions.
