Breakdown of Píanóið í stofunni er mjög stórt.
Questions & Answers about Píanóið í stofunni er mjög stórt.
The base noun is píanó (piano). Icelandic usually does not use a separate word for the; instead it adds a definite ending to the noun.
- píanó = a piano
- píanóið = the piano
The ending -ið tells you two things:
- The noun is neuter (neuter nouns often add -ið in the nominative singular definite).
- It is definite (the specific piano, not just any piano).
So píanóið literally means the piano.
Adjectives in Icelandic must agree in gender, number, and case with the noun they describe.
- píanóið is:
- neuter
- singular
- nominative
The basic adjective is stór (big). In the neuter singular nominative, it takes a -t:
- masculine/feminine nominative singular: stór
- neuter nominative singular: stórt
Because píanóið is neuter, you must say stórt, not stór.
So:
- píanóið er stórt = the piano is big
- stóllinn er stór = the chair (masc.) is big
- taskan er stór = the bag (fem.) is big
The preposition í (in/into) can take dative or accusative, depending on the meaning:
- í
- dative = location (where something is)
- í
- accusative = motion (where something is going)
In this sentence we are talking about location (the piano is in the living room), so í takes the dative:
- stofa (living room, nominative)
- stofu (dative singular, without article)
- stofunni (dative singular definite: in the living room)
If you talked about moving into the living room, you would use accusative:
- Ég fer í stofuna. = I go into the living room.
Stofa is the basic dictionary form (nominative singular):
- stofa = living room
To say in the living room after í (location), you need:
- Dative singular of stofa: stofu
- Add the definite ending for feminine dative singular: -nni → stofunni
So the steps are:
- stofa → stofu (dative) → stofu + nni → stofunni
- í stofunni = in the living room
The neutral word order is Subject – (place/time) – Verb – (other stuff):
- Píanóið í stofunni er mjög stórt.
- Subject: Píanóið í stofunni
- Verb: er
- Predicate: mjög stórt
You can say Í stofunni er píanóið mjög stórt. That is also correct, but it emphasizes the location first: In the living room, the piano is very big.
So both are grammatically fine:
- Píanóið í stofunni er mjög stórt. (more neutral)
- Í stofunni er píanóið mjög stórt. (focuses on in the living room first)
Mjög means very. It is an adverb that intensifies adjectives and some other words:
- mjög stórt = very big
- mjög falleg = very beautiful
- mjög gott = very good
It does not change form; it stays mjög regardless of gender, number, or case. The adjective changes (stór → stórt), but mjög stays the same.
You typically place mjög directly before the adjective:
- er mjög stórt
- er mjög fallegur, etc.
Key points:
- í: like the ee in see (long, tense i).
- á / ó: long vowels.
- ó is like the o in go, but usually a bit tenser.
- ð in píanóið:
- After a vowel at the end of a word, ð is usually soft or almost silent.
- píanóið is roughly [pí-a-no-ith], but the ð is very light, often close to just ending with the vowel.
- Double nn in stofunni:
- Icelandic double consonants are usually long (geminated).
- stofunni is roughly [STO-foonn-i] (with a longer n).
You will hear some variation between speakers, but these are good approximations.
Er is the 3rd person singular form of the verb vera (to be), present tense.
- Ég er = I am
- Þú ert = you are (singular)
- Hann/Hún/Það er = he/she/it is
- Við erum = we are
- Þið eruð = you are (plural)
- Þeir/Þær/Þau eru = they are
In the sentence Píanóið í stofunni er mjög stórt, the subject píanóið is 3rd person singular, so you use er.
The difference is indefinite vs. definite:
- píanó = a piano (any piano, not specific)
- píanóið = the piano (a specific piano that speaker/listener can identify)
Examples:
- Píanó er dýrt hljóðfæri. = A piano is an expensive instrument. (general statement)
- Píanóið í stofunni er mjög stórt. = The piano in the living room is very big. (we know which piano)
In Icelandic, when the noun is definite (has the article ending), an adjective before it normally takes a weak form and often also has a separate definite article:
- stóra píanóið = the big piano
So:
- Píanóið í stofunni er mjög stórt. = The piano in the living room is very big. (adjective in the predicate, strong form)
- Hið stóra píanó í stofunni = the big piano in the living room (more formal, adjective before noun with separate article hið).
Your suggested stórt píanóið (with -t and the definite ending -ið) is not the normal way to say the big piano. You would use stóra píanóið instead.
