A pronominal adverb is a type of adverb occurring in a number of Germanic languages, formed in replacement of a preposition and a pronoun by turning the former into a prepositional adverb and the latter into a locative adverb, and finally joining them in reverse order.
For example: In modern English, pronominal adverbs are most commonly encountered in literary registers or in legal usage.
For this reason, pronominal adverbs are often seen as a type of legal jargon.
In Dutch, pronominal adverbs are very common and are almost mandatory in many situations; neglecting to use them often makes a phrase sound unnatural to native speakers.
This distinction is faithfully reflected in the use of pronominal adverbs, and other pronouns also often have a corresponding adverbial form.
