Introduction

A and an introduce one non-specific singular countable noun. The identifies a noun that speaker and listener can locate from context, previous mention, shared knowledge, or uniqueness. Zero article is used in many general and institutional expressions.

The choice between a and an depends on the first sound, not the first written letter.

Definition

Articles are determiners that show whether a noun is introduced generally, identified specifically, or used without an article.

The definition should be applied through meaning and context. In objective examinations, two forms may appear structurally possible, but only one expresses the intended relationship accurately.
