• Synonyms Final, Eventual, Ultimate, Conclusive. Final, coming at the end or at last, marks mainly the circumstance of being the last or at the last. Eventual has reference rather more to the outcome of events. Ultimate is like eventual in that respect: an ultimate object is that to which all one's actions tend as their aim and crowning point; in this sense it is a sort of superlative, with ulterior as the corresponding comparative. Conclusive, like decisive, is active; it means final by closing or settling, putting a stop to any further question or procedure: as, a conclusive argument, step, decision.
• noun That which is last; that which forms an end or termination; specifically, in Gregorian music, the tone in each mode with which melodies must end: in authentic modes the lowest tone, and in plagal modes the fourth tone from the bottom. The final corresponds in part to the modern key-note or tonic.
