Isleno Spanish speakers maintain few contexts firmly in the subjunctive (for example, adverbial clauses with the conjunctions "para que" and "antes que" and nominal clauses with "querer"), with most other semantic or syntactic categories optionally licensing the subjunctive. This study will outline the obligatory and optional uses of present and past subjunctives in Isleno Spanish to show that fluent speakers utilize the verb forms as resources to manage the semantic/pragmatic meanings of doubt, negation, and expressions of will, as well as their discursive stances of solidarity or individuality.
