In medieval logic, syncategoremata are words which are not categorematic: they cannot be used on their own as a subject term or as a predicate term. Syncategorematic terms can occur in a categorical or hypothetical proposition only with at least one matched pair of categorematic words – e.g., only Socrates runs (Solus Socrates currit), Socrates does not run (Socrates non currit).
More than fifty different words were considered in the medieval logicians' treatment of syncategoremata.
