Lojban has incorporated a detailed grammar for mathematical expressions. This grammar parallels the predicate grammar of the non-mathematical language.

My advice is predicated on my experience.

'Verb' refers to the predicate verb. Predicate verbs change their form depending on the subject and the time expressed.

Should we exercise yet how to translate sentences containing a subject, a predicate and an object? Or should we go further?

This sentence has a predicate but no subject.

The sentence must have a predicate.
