Enquanto eu semeio e rego, eles podam.

Enquanto means while or whilst. It introduces an action happening at the same time as another action.

So in Enquanto eu semeio e rego, eles podam, the idea is:

• while I sow and water
• they prune

It links the two simultaneous actions.

Because semeio is the 1st person singular form of the verb semear in the present indicative:

• eu semeio = I sow
• tu semeias
• ele/ela semeia
• nós semeamos
• vós semeais
• eles/elas semeiam

So semeio matches eu.

Rego is the 1st person singular present form of regar:

• eu rego = I water
• tu regas
• ele/ela rega
• nós regamos
• vós regais
• eles/elas regam

Since the subject is eu, rego is the correct form.

Podam is the 3rd person plural present form of podar:

• ele/ela poda = he/she prunes
• eles/elas podam = they prune

Since the subject is eles, the verb must be podam.

Not always. Portuguese often drops subject pronouns because the verb ending usually makes the subject clear.

So you could also say:

• Enquanto semeio e rego, eles podam.
• Enquanto eu semeio e rego, podam.
• Enquanto semeio e rego, podam.

However, including eu and eles can add clarity, contrast, or emphasis. In this sentence, using both pronouns makes the contrast between I and they especially clear.

In Portuguese, the simple present can describe:

• habitual actions
• general truths
• actions in a narrative or descriptive sense
• sometimes actions happening now, especially when context makes it clear

So Enquanto eu semeio e rego, eles podam is a perfectly natural way to express the idea.

If you wanted to stress that the actions are happening right now, European Portuguese often prefers the structure:

• Enquanto eu estou a semear e a regar, eles estão a podar.

But that is more explicit and heavier. The original sentence sounds more general, concise, and natural in many contexts.

Yes. That is very common.

After enquanto, Portuguese can use the indicative when referring to a real or actual situation:

• Enquanto eu trabalho, ele descansa.
• Enquanto chove, ficamos em casa.

So Enquanto eu semeio e rego, eles podam is grammatically straightforward.

Because both verbs have the same subject: eu.

Portuguese, like English, does not need to repeat the subject when one subject performs two coordinated actions:

• eu semeio e rego = I sow and water

You could think of it as:

• eu semeio e eu rego

but the second eu is normally omitted because it would sound repetitive.

Yes. E simply means and. It just links the two actions:

• semeio e rego = I sow and water

If you said e também, it would add extra emphasis, closer to and also:

• semeio e também rego

That is possible, but the original sentence is simpler and more natural unless you specifically want emphasis.

Podar mainly means to prune, especially in gardening, farming, or caring for plants and trees.

Examples:

• podar uma árvore = to prune a tree
• podar roseiras = to prune rose bushes

It can also be used more broadly in figurative contexts, but for learners the main meaning is definitely the gardening one.

In this context, regar means to water plants or crops.

Examples:

• regar as plantas = to water the plants
• regar o jardim = to water the garden

In some contexts, it can also mean to irrigate, depending on scale.

In European Portuguese, semeio is roughly pronounced like suh-MAY-yoo, though English spelling can only approximate it.

A few useful points:

• the stress falls on mei
• the final o in European Portuguese is often reduced, sounding closer to u
• the first e is usually fairly reduced in connected speech

So it will not sound like a fully clear English-style seh-MEH-ee-oh.

The comma separates the subordinate clause introduced by enquanto from the main clause.

Structure:

• Enquanto eu semeio e rego = subordinate clause
• eles podam = main clause

This punctuation helps readability. In short sentences, punctuation can vary a little, but the comma here is very normal and helpful.

Yes, absolutely.

Both are correct:

• Enquanto eu semeio e rego, eles podam.
• Eles podam enquanto eu semeio e rego.

The meaning stays basically the same. The difference is mainly one of focus:

• starting with Enquanto... foregrounds the time relationship
• starting with Eles podam... foregrounds what they do

By itself, it could be understood either way, depending on context.

It can describe:

• a repeated routine: While I sow and water, they prune
• a scene being described: While I’m sowing and watering, they prune

The simple present in Portuguese is flexible enough for both. Context tells you which is meant.

Sometimes, yes. In many contexts, enquanto can be translated as while or as, depending on what sounds most natural in English.

For example:

• Enquanto eu semeio e rego, eles podam. could be understood as:
• As I sow and water, they prune.

But while is usually the clearest and safest translation for learners.
