Zero-marking in English is the indication of a particular grammatical function by the absence of any morpheme (word, prefix, or suffix). The most common types of zero-marking in English involve zero articles, zero relative pronouns, and zero subordinating conjunctions. Examples are I like cats in which the absence of the definite article, the, signals cats to be an indefinite reference, whose specific identity is not known to the listener; that's the cat I saw in which the relative clause (that) I saw omits the implied relative pronoun, that, which would otherwise be the object of the clause's verb; and I wish you were here. in which the dependent clause, (that) you were here, omits the subordinating conjunction, that.
