Definition

1. Noun:
   • A violently rotating column of air: A tornado is a rapidly spinning, funnel-shaped column of air that extends from a thunderstorm cloud to the ground. It is characterized by extremely high wind speeds and the potential for catastrophic damage.
   • A localized and violently destructive windstorm: This refers specifically to the meteorological phenomenon occurring over land, distinguished by its funnel cloud and intense, concentrated destructive power.

Usage

• The word "tornado" is a countable noun. It is used to describe the specific, powerful storm itself.
• It is typically modified by adjectives describing its intensity, size, or location (e.g., a tornado, an tornado, a tornado).

Examples
