are used in a variety of ways. Syntactic approaches to this common element have attempted to find a universal way of handling them. For example, all languages are capable of having subjects, objects, and verbs, so a universal methodology to handling word order, whether SVO, VSO, or OSV, is imperative for a multilingual and universal syntactic representation system to work. As such, there has been great discussion and investigation in the literature for that particular word order element. Clitics, on the other hand, have been given relatively less thought and investigation, particularly an inquiry into an uncomplicated approach in their syntactic distribution. Clitics offer a myriad of functional roles depending upon the language in question, further complicating the situation. Spanish is a diasporic language which also experiences diachronic variation. While Spanish is said to generally have flexible or "free" word order, others such as Pountain assert that the syntax is heavily influenced by topic and comment identification. Historical approaches The syntactic role of the clitic and its forms in Spanish has undergone much debate within the research with no obvious conclusion. Part of the difficulty stems from the variable role and its other forms play with regard to the contextual grammar. Some syntacticians have aptly termed the clitic as "paradigmatic" in reference to the complexity and variance of features and functions. It is utilized in a variety of Spanish grammar contexts, including the following forms: reflexive pronoun, reciprocal pronoun, replacive pronoun (direct and indirect object), intrinsic pronoun (without the pronoun, the structure is ungrammatical), "derivational" pronoun, and "stylistic" pronoun. Further, is used in addition with certain intransitive verbs, in reflexive-passive constructions, and in impersonal constructions. As a class, clitics have such a variety of grammatical functions that they are not always pronominal, anaphoric or related to verbal arguments. Syntactically, they are most often found in non-argument benefactive theta-roles, in formation of passive, in formation of middle voice, and with a completive meaning. They can take the form of either phrasal constituents or words with an independent syntactic structure. Despite being grammatically diverse in Spanish grammatical application, it does certain specific roles. Zagona, author of a comprehensive Spanish syntax textbook, has extensively outlined form and function in depth, stating that: [sic] the only true subject clitic in Spanish is "impersonal" "one". The impersonal form is clearly defined as it does not double and uses only the third person singular verb form
