The Lexical Uses of Be, Have and Do: Three Small Verbs with Big Power

In English, there are three verbs that seem simple but appear everywhere: be, have, and do.
Many English learners know them only as auxiliary verbs, the ones that help other verbs form tenses (for example: The cows are eating; She has been checking the barn; We don’t sell calves before six months).
However, they also have lexical uses, meaning they can function as main verbs that express meaning on their own.

In the world of farming, where routine and responsibility rule, understanding these verbs can make the difference between a correct sentence and one that sounds awkward.
Let’s look at how to use them with examples from the daily life of a livestock handler: someone responsible, careful, and always ready to act before things get out of control.

“Be”: The Verb of Being and Existing

The verb be tells us who we are, how we feel, or where we are. It describes states, identities, and conditions.
Its main forms are: am, is, are, was, were, be, been, being.

Imagine a farmer observing their land at sunrise. They might say:

“I am a responsible livestock handler.”
(I am a responsible livestock handler.)

That simple sentence expresses identity. Am is not helping any other verb; it carries its own meaning.

Another practical example:

“The cows are healthy.”
(The cows are healthy.)

Here, are describes a physical or health condition, something very important when working with dairy cattle.

In the past, we can use was or were:

“The bull was very aggressive before feeding time.”
(The bull was very aggressive before feeding time.)

And if we want to talk about a constant behavior:

“Being calm is part of the job.”
(Being calm is part of the job.)

In this case, being acts as a noun (gerund) and represents a quality or attitude.
In short, be describes the state of the subject, whether physical, mental, or situational. If be is followed by an adjective or a noun, it’s functioning as a main verb.

“Have”: The Verb of Possessing, Experiencing, and Enjoying

If be is about who you are, have is about what you own or experience.
Its forms are have, has, had.

For example, a farmer might say:

“We have twenty dairy cows.”
(We have twenty dairy cows.)

Here, have expresses literal possession. But it can also refer to everyday activities:

“She has breakfast before checking the barn.”
(She has breakfast before checking the barn.)

In this case, has means performing a regular activity, such as eating or meeting.
It can also refer to experiences or situations:

“They had a problem with the new milking machine.”
(They had a problem with the new milking machine.)

Sometimes it even has an idiomatic sense. In English, the expression cash cow may sound literal, but it means a reliable source of income.

“Healthy dairy herds are a real cash cow.”
(Healthy dairy herds are a real cash cow.)

In rural life, that makes perfect sense: if your cows are healthy, your income is too.

Have is also used to express obligation or responsibility when we say have to:

“You have to be responsible with feeding times.”
(You have to be responsible with feeding times.)

Although it looks auxiliary, have here still keeps its lexical meaning because it expresses a personal or practical necessity.

“Do”: The Verb of Work and Action

Finally, we have do, the verb of pure action.
Forms: do, does, did.

A good livestock handler does many things in one day, and this verb shows it:

“I do my chores early in the morning.”
(I do my chores early in the morning.)

“He does the milking carefully every day.”
(He does the milking carefully every day.)

The word carefully shows that the action is done with attention, which is essential when working with animals.

In the past tense:

“They did the vaccination last week.”
(They did the vaccination last week.)

And if someone gets too excited, you can say:

“Hold your horses before you do anything crazy!”
(Hold your horses before you do anything crazy!)

The expression hold your horses literally means “hold your horses,” but idiomatically, it means “wait” or “don’t rush.” It’s quite useful when someone is about to open the gate too early or release the animals without checking.

Do can also express personal effort:

“She does her best to keep the animals healthy.”
(She does her best to keep the animals healthy.)

In short, do is the verb of doing, of daily work, of concrete action.

Comparing the Three

To keep it simple:

• Be describes who you are or how you feel.
• Have shows what you own or experience.
• Do expresses what you do.

A farmer could sum up their day like this:

“I am a responsible farmer, I have healthy cows, and I do my work carefully.”

In one sentence, all three primary verbs are used with their full meaning — a mini English lesson inside a day of honest work.

Final Reflection

Learning the lexical uses of these three verbs is like learning the basic movements before riding a horse. They may seem simple, but everything depends on them.
Mastering be, have, and do allows you to describe your reality, responsibilities, and actions precisely. And that is essential both in the field and in the classroom.

So, next time you talk about your cows, your farm, or your daily routine, remember to use these verbs with intention.
Because in English, just like in farming, what you are, what you have, and what you do say everything.
