What is a zero?

Definition

Here are two senses for zero:

  1. A zero is a constituent proposed in an analysis to represent an element held to be present at an abstract level but not realized in the data.

Examples (English)

  • A zero realization of a semantic argument proposed for the second clause in I eat breakfast before 7 A.M.; John eats Ø about 8 A. M.
