Predicate

• Predicates can be one verb or verb phrase (simple predicate), two or more verbs joined with a conjunction (compound predicate), or even all the words in the sentence that give more information about the subject (complete predicate)

Question

• [-] Is a simple predicate still a relation? I've seen where people say that a unary relation is basically a reflexive/recursive relationship, like "i slapped myself", as opposed to a property like, "i slept".

Ideas

• predicate arguments can have Thematic Roles

  • It is often convenient to identify arguments of (Fregean) predicates in terms of the following thematic roles, which are illustrated below.
