"pro-drop language"의 정의 및 의미

What is a "pro-drop language"?

A pro-drop language is a type of language in which it is common to omit pronouns when they can be understood from the context. In these languages, the subject pronoun is often not necessary for clarity and can be dropped without causing confusion. For example, in Spanish, one might say "Voy al mercado" which translates to "I go to the market," but the subject "I" is not stated. This is because the verb form "voy" indicates that the subject is first-person singular. Pro-drop languages, like Italian, Portuguese, and Persian, often have verb forms that provide enough information about the subject, allowing for this omission. In contrast, languages like English typically require the use of pronouns for clarity, making them non-pro-drop languages.
