Αν η μαγιά δεν είναι καλή, το μίξερ δεν βοηθάει πολύ και το ψωμί δεν βγαίνει καλό.

Αν means if. It introduces a condition:

• Αν η μαγιά δεν είναι καλή = If the yeast is not good

This is a very common Greek way to make if sentences. In this sentence, αν is followed by the present tense because it is talking about a real or general condition, not something imaginary or impossible.

The comma separates the if-clause from the main clause, just like in English:

• If the yeast is not good, the mixer does not help much...

In Greek, when the conditional clause comes first, a comma is normally used.

Greek uses the definite article very often, even in places where English might or might not use the.

Here:

• η μαγιά = the yeast
• το μίξερ = the mixer
• το ψωμί = the bread

In Greek, nouns are normally used with an article unless there is a specific reason not to. So to an English speaker, Greek can sound more article-heavy.

Also, the articles show gender and case:

• η = feminine singular nominative
• το = neuter singular nominative

Δεν is the basic word for not before verbs in ordinary statements.

So:

• δεν είναι = is not
• δεν βοηθάει = does not help
• δεν βγαίνει = does not come out / does not turn out

Greek does not use a separate word like English do for negation. You simply put δεν before the verb.

Because adjectives must agree with the noun they describe in gender, number, and case.

• η μαγιά is feminine singular, so the adjective is καλή
• το ψωμί is neuter singular, so the adjective is καλό

So:

• καλή μαγιά = good yeast
• καλό ψωμί = good bread

This agreement is a very important feature of Greek grammar.

Here πολύ is an adverb, meaning much / a lot. It modifies the verb βοηθάει:

• δεν βοηθάει πολύ = it does not help much

When πολύ is an adverb, it stays πολύ.

Compare that with the adjective forms:

• πολλός = much/many, masculine
• πολλή = much/many, feminine
• πολύ = much, neuter adjective form

But in this sentence it is not describing a noun. It is describing how much the mixer helps, so the adverb πολύ is correct.

Βγαίνω literally means go out / come out, but it is very often used in Greek for things like food, results, and outcomes:

• Το ψωμί βγαίνει καλό = The bread comes out good
• more naturally in English: The bread turns out good

So Greek uses βγαίνει where English often uses turns out rather than just is.

This is a very natural expression in Greek cooking and everyday speech.

Yes, είμαι = I am is an irregular verb, and είναι is one of its forms.

Present tense of είμαι:

• είμαι = I am
• είσαι = you are
• είναι = he/she/it is
• είμαστε = we are
• είστε = you are
• είναι = they are

So in η μαγιά δεν είναι καλή, είναι means is because the subject is singular.

Yes. Both βοηθάει and βοηθά are used.

They are two common present-tense forms of the same verb:

• βοηθάει
• βοηθά

Both mean helps / is helping.

So these are both natural:

• Το μίξερ δεν βοηθάει πολύ
• Το μίξερ δεν βοηθά πολύ

The version with -άει can sound a bit more explicit or traditional in full form, but both are standard.

Yes, μίξερ is a loanword, and many borrowed nouns in Greek are treated as neuter, especially objects and machines.

So:

• το μίξερ

Its form does not change much, but the article tells you its gender and case.

This is very common with modern borrowed words in Greek.

Greek word order is fairly flexible, but this order is the most neutral and natural:

• Subject + δεν + verb + adverb

So:

• το μίξερ = subject
• δεν βοηθάει = does not help
• πολύ = much

You could change the order for emphasis, but the given version is the straightforward one.

Because Greek verbs already show the person and number, and the subject is usually stated only when needed.

In this sentence, the nouns themselves are the subjects:

• το μίξερ δεν βοηθάει πολύ
• το ψωμί δεν βγαίνει καλό

Greek does not need an extra subject pronoun like English it here.

It most naturally sounds like a general truth or a practical observation:

• If the yeast is not good, the mixer does not help much and the bread does not turn out good.

Using the present tense in both parts often gives that general, habitual meaning in Greek.

It could also apply to a specific situation depending on context, but without more context it sounds like general advice or common knowledge.
