Simile is a SD based on a deliberate comparison of two objects, belonging to two different classes. This trope is easy to recognize because of the form words, used to connect the compared objects: ‘like’, ‘as though’, ’as if’, ‘as…as’, ‘such as’, ‘seem’, etc.

Simile is used for the purpose of expressive evaluation, emotive explanation and highly individual description.
