Resumen de Allomorphy and suppleion
This chapter provides an overview of different types of allomorphic alternations in Spanish and what triggers them. It highlights four important issues that have been instrumental in informing analyses of suppletive allomorphy from various perspectives. The terms allomorphy and suppletion both refer to a situation in which a single grammatical feature or a single lexeme has more than one phonological exponent. Such exponents are said to exhibit an allormorphic or suppletive alternation, which is conditioned by some linguistic context. Suppletive allomorphy in roots and stems is pervasive in Spanish. The trigger is the conditioning environment that determines which exponent in a suppletive allomorphic alternation will be spelled out. Triggers may be phonological, morphological, lexical or syntactic in nature. Since much theoretical discussion about suppletive allomorphy is based in part on locality constraints between the trigger and target, it is worth mentioning two types of distance relations: local and non-local.
