Kierowniczka obiecała, że w tym miesiącu będzie lepsza wypłata i mała premia.

Yes. Kierowniczka is the feminine noun meaning a female manager/supervisor.

• masculine: kierownik
• feminine: kierowniczka

Polish often marks the person’s gender directly in the noun, especially for job titles, though usage can vary depending on style and context.

Because the subject is feminine singular: kierowniczka.

In the past tense, Polish verbs agree with the gender and number of the subject:

• obiecał = he promised
• obiecała = she promised
• obiecało = it promised
• obiecały / obiecali = they promised

So kierowniczka obiecała is the correct match.

Also, obiecała comes from the perfective verb obiecać, which fits well because promising is treated as a completed act.

Because in Polish, a comma is normally required before że when it introduces a subordinate clause.

Here, że means that and starts the content of the promise:

• Kierowniczka obiecała, że...
• The manager promised that...

This comma is standard and expected in written Polish.

Że introduces a subordinate clause, just like that in English.

So the structure is:

• Kierowniczka obiecała = The manager promised
• że w tym miesiącu... = that this month...

It links the main clause to what was promised.

Because the preposition w meaning in takes the locative case when it refers to location or time.

So:

• nominative: ten miesiąc
• locative: w tym miesiącu

This is the normal pattern for time expressions like in this month → w tym miesiącu.

Będzie is the 3rd person singular future form of być = to be.

It is used because the promised situation is in the future:

• jest = is
• będzie = will be

So the manager promised that later, in that month, there will be a better paycheck and a small bonus.

This is a very good question.

Many learners notice that wypłata i mała premia are two coordinated nouns, so they expect plural będą. In careful, textbook-style agreement, będą is often the safer choice:

• ...będą lepsza wypłata i mała premia.

However, singular będzie can also be heard, especially when the clause has an existential sense similar to English there will be..., and the nouns come after the verb.

So:

• będą = more strictly agreement-based
• będzie = possible in real usage, especially in a more general there will be sense

If you want the most straightforward learner-friendly version, będą is probably the form to remember.

Because both adjectives agree with feminine singular nouns in the nominative:

• wypłata is feminine singular, so lepsza wypłata
• premia is feminine singular, so mała premia

Polish adjectives must agree with the noun in:

• gender
• number
• case

That is why you do not get forms like lepszy wypłata or mały premia.

Because they function as the nouns linked to będzie / będą in a clause meaning roughly there will be...

After być in this kind of sentence, the noun phrase is normally in the nominative:

• będzie premia
• będzie wypłata
• będą zmiany

So lepsza wypłata and mała premia stay in nominative forms.

It is understandable, but many native speakers might more naturally say wyższa wypłata if they mean the amount of pay is larger.

A useful distinction is:

• lepszy / lepsza = better in a general sense
• wyższy / wyższa = higher, larger in amount

So if the idea is specifically more money, many speakers would prefer:

• wyższa wypłata

Still, lepsza wypłata is not impossible; it just sounds a bit less precise.

These words are related but not identical.

• wypłata = pay, payout, paycheck, the money you receive from work
• pensja = salary, regular pay as a fixed employment amount
• premia = bonus

So:

• wypłata can focus on the actual payment received
• pensja often refers more to your salary as a regular wage
• premia is extra money in addition to normal pay

In this sentence, wypłata + premia means the person expects both a better regular payment and an extra bonus.

Yes. Polish word order is fairly flexible, and changing it usually changes emphasis rather than the basic meaning.

For example:

• Kierowniczka obiecała, że w tym miesiącu będzie...
• Kierowniczka obiecała, że będzie w tym miesiącu...

Both are possible, but w tym miesiącu earlier in the clause sounds natural because it sets the time frame right away.

Polish often moves elements around to highlight what is new, important, or contrasted.

Because Polish has no articles.

English distinguishes:

• a bonus
• the bonus

Polish simply uses the noun:

• premia

Whether it should be understood as a or the depends on context. Learners coming from English often look for an article, but Polish does not have one.
