Could: The Modal Verb of Past Ability, Polite Requests, and Hypothetical Scenarios

In the English language, modal auxiliary verbs play a crucial role in expressing various meanings and functions. Among these modals, could stands out as a versatile and important verb with a wide range of applications. Let's explore the multifaceted nature of could and examine how it is used to convey past ability, possibility, politeness, hypothetical scenarios, and much more.

Expressing Past Ability

One of the primary uses of could is to express past ability. When we use could in this context, we refer to someone's skill or capacity to do something in the past. For example:
