המכונה פועלת טוב.

A common pronunciation is:

ha-mekhona po-élet tov

A more detailed breakdown:

• המכונה = ha-mekho-NA
• פועלת = po-E-let
• טוב = tov

A rough full pronunciation: ha-mekhona po-E-let tov

Notes:

• ch in mekhona is like the Hebrew letter כ/ח, a throaty sound that does not really exist in standard English.
• Stress usually falls near the end:
  • mekhoNA
  • poElet

The ה is the Hebrew definite article, meaning the.

So:

• מכונה = machine
• המכונה = the machine

Unlike English, Hebrew attaches the directly to the noun as a prefix.

Because מכונה is a grammatically feminine noun in Hebrew.

That matters because Hebrew verbs in the present tense agree with the subject in gender and number. Since המכונה is feminine singular, the verb is also feminine singular:

• פועל = masculine singular
• פועלת = feminine singular

So המכונה פועלת is grammatically matched.

פועלת is the feminine singular present-tense form of the verb לפעול, which means to operate, to function, or to act.

So:

• אני פועל / פועלת = I operate / act / function
• הוא פועל = he operates
• היא פועלת = she operates
• המכונה פועלת = the machine operates / is operating / functions

In modern Hebrew, the present tense is built from forms that historically behave a bit like participles, but for learners it is usually simplest to think of פועלת here as a normal present-tense verb form.

Because Hebrew does not build the present tense the way English often does.

In English, you may say:

• The machine operates
• The machine is operating

In Hebrew, a single present-tense form like פועלת can cover both ideas, depending on context.

So המכונה פועלת can mean:

• The machine operates
• The machine is operating
• The machine works

Because here טוב is functioning like an adverb, meaning well, not like an adjective meaning good.

Compare:

• מכונה טובה = a good machine / the machine is good
  Here טובה must agree with the feminine noun מכונה.

But in your sentence:

• המכונה פועלת טוב = the machine works well

Here טוב describes how it operates, so it does not agree with מכונה.

Important note: In formal or more standard Hebrew, many teachers prefer:

• המכונה פועלת היטב

because היטב is the more traditionally standard word for well.

However, in everyday spoken Hebrew, טוב is very commonly used in this adverb-like way.

Yes, it is understandable and fairly natural, especially in everyday speech.

But there are a couple of things to know:

1. Colloquial everyday Hebrew often allows:

   • פועלת טוב = works well

2. More formal / standard Hebrew often prefers:

   • פועלת היטב

3. Many speakers might also say:

   • המכונה עובדת טוב
   • literally the machine works well

That version with עובדת is often very common in conversation.

So all of these are possible, but they differ a little in style:

• המכונה פועלת טוב = natural, understandable, somewhat neutral/colloquial
• המכונה פועלת היטב = more standard/formal
• המכונה עובדת טוב = very common in speech

Both can describe a machine functioning, but the feeling is a little different.

• פועלת comes from לפעול = to operate / function
• עובדת comes from לעבוד = to work

For a machine, both can be translated as works.

Very roughly:

• המכונה פועלת sounds a bit like the machine is operating / functioning
• המכונה עובדת sounds a bit like the machine is working

In many everyday contexts, the difference is small, and native speakers may use either one.

Yes, but המכונה פועלת טוב is the basic, neutral order.

This order is:

subject + verb + adverb/complement

• המכונה = subject
• פועלת = verb
• טוב = describes how it operates

You might sometimes hear different word orders for emphasis, but the standard learning-friendly version is exactly this:

המכונה פועלת טוב

It comes from the root פ-ע-ל.

This root is very common in Hebrew and is connected to ideas like:

• acting
• operating
• functioning
• activity

Related words include:

• פועל = worker / operates / acts
• פעולה = action, operation
• פעיל = active

So seeing פועלת can also help you recognize this broader word family.

The present-tense verb changes to match the subject.

With the verb לפעול:

• פועל = masculine singular
• פועלת = feminine singular
• פועלים = masculine plural
• פועלות = feminine plural

Examples:

• המנוע פועל טוב = the engine works well
  (מנוע is masculine)

• המכונה פועלת טוב = the machine works well
  (מכונה is feminine)

• המכשירים פועלים טוב = the devices work well
  (masculine plural)

This agreement is one of the key features of Hebrew grammar.

No. You do not need a separate pronoun.

Hebrew usually does not add a pronoun when the noun itself is already stated.

So you say:

• המכונה פועלת טוב

not:

• המכונה היא פועלת טוב

That second version would sound wrong in normal Hebrew.

The noun המכונה already gives the subject, and פועלת already shows feminine singular agreement, so everything needed is already there.
