ABSTRACT
Prepositions indicate a relationship between a noun in a phrase immediately following it and some other noun or verb in the sentence. The object of a preposition is the noun or noun phrase immediately following it; mutation effects and/or case marking of the object noun follow from this closeness. Simple prepositions are unstressed and often, though not always, cause a mutation on their noun objects. In some cases they may contract with a definite article or other determiner. The mutations identified in the list apply only when a bare noun, such as a proper name or an indefinite form, immediately follows the preposition. Full paradigms for all the inflected prepositions, plus a few less common ones, are readily available in any grammar of Irish with a focus on morphology. Still other prepositions are more complex in form, consisting usually of a simple preposition and a noun. These are called compound prepositions.
