With the modernization taking place globally, language also has updated itself with the English language showing supremacy worldwide.

It is one of the oldest and most widely spoken languages globally. English has made communication way better between different countries by being an international language.

English has eight parts of speech that help form sentences and make them easier to understand.

Key Takeaways

1. “Could” indicates the ability or possibility of acting, suggesting something is feasible within the realm of possibility.
2. “Might” implies a lower probability level than could and suggests that something is possible but not necessarily likely to happen.
3. “Could” suggests a greater degree of control or agency in acting, while “might” conveys a sense of uncertainty or unpredictability.

Could vs Might

“Could” is used to express a past or present possibility. It is also used to express ability in the past. For example: “I could run faster when I was younger” or “It could rain tomorrow.” “Might” is used to express a future possibility. It expresses a more remote or uncertain possibility than “could.” For example: “It might snow tomorrow” or “She might arrive late.

Could is the past tense of ‘can’. It is used to describe an ability or a possibility. It is used when someone refers to an ability in the past and acts as a conditional verb expressing power or past potential.

For example, In middle school, I could play Table tennis. It is used as a modal or helping verb to describe a possibility in the present and future tense.

Might- refers to a situation or an event that has a possibility of occurrence, but the occurrence of the situation or event is not entirely assured. E.g. Shweta might go to Jaipur next.

Here, there is a chance of happening of the event, but the speaker uses it to express a rare chance that it may or may not occur.
