Learn Hardcore Polish: To jest mój drugi dom.

Correct: To jest mój drugi dom.
If you name the noun first, you use a gendered determiner: Ten dom jest mój.
Incorrect: Ten jest mój dom. (you can’t put ten before jest without the noun)

Why is it mój, not moja or moje?

Because dom is masculine inanimate, and adjectives/possessives must agree in gender, number, and case. In the nominative singular:

masculine inanimate: mój dom
feminine: moja książka
neuter: moje okno

Why is everything in the nominative? Doesn’t Polish use instrumental after “to be”?

With the pattern To jest + noun, the predicate noun stays in the nominative: To jest mój drugi dom.
But when the subject isn’t to (e.g., starts with the noun), Polish typically uses the instrumental for a noun complement:

Ten dom jest moim drugim domem.
Compare people:
To jest mój brat. (nominative after to jest)
On jest moim bratem. (instrumental after jest)

Can I drop jest?

Yes. To mój drugi dom. is common and perfectly natural, slightly more colloquial or emphatic than To jest mój drugi dom.

Can I change the word order?

Natural: To (jest) mój drugi dom.
Also natural (without jest): To mój drugi dom.
Unnatural: To jest mój dom drugi. (adjectives like ordinals precede the noun)
Marked/emphatic, rare: To jest drugi mój dom. (puts focus on “drugi”)

Does drugi ever mean “other,” not just “second”?

Yes. Drugi normally means “second,” but it can mean “the other (of two).”

Weź drugą rękawiczkę. = “Take the other glove.”
For “other/different” in general, use inny: inny dom = “a different/another house.”

What’s the nuance of dom: “house” or “home”?

Dom can mean both. Context decides:

Physical building: “house.”
Emotional/figurative: “home.”
So To jest mój drugi dom. can mean a second residence (e.g., vacation home) or “a place I feel at home.” For an apartment, use mieszkanie.

How do I pronounce the sentence?

To [tɔ]
jest [jɛst] (initial j like English “y” in “yes”)
mój [muj] (ó = [u])
drugi [ˈdruɡi] (stress on DRU; “g” as in “go”)
dom [dɔm]
Polish stress is generally on the penultimate syllable of each multi‑syllable word (e.g., DRU‑gi).

How do I negate it?

With jest: To nie jest mój drugi dom.
Without jest: To nie mój drugi dom.
Both are fine; the version with jest can feel a bit more explicit or neutral.

How do I make it a question?

Neutral yes/no: Czy to jest mój drugi dom?
Colloquial intonation question: To jest mój drugi dom? or To mój drugi dom? (rise in pitch at the end)

How do the words change in other cases?

A few common ones:

Accusative (seeing): Widzę mój drugi dom.
Genitive (to, of): Idę do mojego drugiego domu.
Locative (in, at): Jestem w moim drugim domu.
Instrumental (with/as): Z moim drugim domem.

Is the order “mój drugi dom” fixed, or could it be “drugi mój dom”?

Default is determiner/possessive before the ordinal: mój drugi dom.
drugi mój dom is possible but marked, usually for emphasis or in stylistic/poetic contexts.

What’s the difference between drugi, następny, and kolejny?

drugi = specifically “second” (2nd in order).
następny = “next” (the following one).
kolejny = “another/additional” or “subsequent” (not tied to the number 2).
So “my second home” is mój drugi dom, not następny/kolejny dom (unless you mean “another home” vaguely).

How would I say it in the plural?

“These are my second homes” = To są moje drugie domy.
Note the plural verb są and agreement: moje drugie (non‑masculine‑personal plural) with domy.
