This paper will examine the use of prefixed verb forms in Phoenician in relation to modality. I will compare the use of the jussive with the prefixed verb forms (subjunctives) used in conditional clauses. Salient indicators that help distinguish the use of the jussive and subjunctive, as well as issues surrounding fronting and triggers (including relative and conditional particles) will be discussed in defining the functions of modal prefixed verb forms in Phoenician inscriptions.
