If you’ve ever hesitated in a conversation, wondering whether to say would, could, or should. Then you’re not alone. These three small words are modal verbs. They are special verbs in English. They express possibility, ability, advice, permission, or hypothetical situations. They’re short. But they can completely change the meaning of a sentence.
Learning proper use of would, could, and should will make you speak and write better, more respectfully and more accurately both in speech and on paper.
You’ll learn here what these words do, how to do it, the most common errors to avoid, and many useful examples.
Why Would, Could, and Should Should be in English
The masters of English language speech are these modal verbs. They help you:
- To make polite requests
- To speak of possibilities
- To give advice
- To speak of impossible or imaginary circumstances
- To speak of past ability or missed chances
Without them, your speech will be too blunt, one-sided, or even insulting.
Example:
Without modal: I help you. (Says something incorrect, i.e., statement and not an offer)
With modal: I could help you. (Sounds like an offer or a possibility)
What Are Modal Verbs
Modal verbs support auxiliary verbs that add to the meaning of the principal verb. They never change their form according to the subject, and always precede the base form of the principal verb (without to).
Examples:
- I would like tea.
- She could run faster when she was young.
- You should visit a doctor.
Knowing “Would”
Hypothetical Situations
Would is used to state something that does not exist or is not real.
Examples:

She’d help you if she were there.
Making or Requesting Politely
Would make or make an offer or a request polite.
Examples:
Would you kindly have a cup of coffee?
I.d be happy to help you.
Referring to the Future in the Past
We would use would every time we are talking about something in the future from a past position.
Examples:

Habits in the Past
Would can indicate repetition in the past, though.
Examples:

Discussion of Hypothetical Possibilities

Uncertainty
May can express that something is likely to occur but is not definitely sure.

Understanding “Should”
Advising or Making Suggestions

We use should in attempting to tell one what is expected or should normally occur.
Examples:
