Breakdown of Lykillinn hlýtur að vera í geymslunni, því ég setti hann þar í gær.
Questions & Answers about Lykillinn hlýtur að vera í geymslunni, því ég setti hann þar í gær.
-inn is the suffixed definite article in Icelandic (roughly “the”).
So lykill = “key” (indefinite), while lykillinn = “the key” (definite).
It attaches to the noun and triggers some spelling/ending patterns depending on the noun’s declension.
hlýtur is the 3rd person singular present tense of hljóta. In this construction hlýtur að + infinitive, it expresses a strong inference/necessity (“must”, “is bound to”, “has to be (the case)”).
So Lykillinn hlýtur að vera... is “The key must be...”, often implying the speaker is concluding it based on evidence (e.g., “because I put it there”).
After many verbs (including hljóta in this meaning), Icelandic commonly uses að as an infinitive marker, similar to English “to”.
So hlýtur að vera = “must to be” in structure, i.e. “must be”.
Because hlýtur is the finite (conjugated) verb of the clause, and the following verb stays non-finite (infinitive).
Pattern: finite verb + að + infinitive → hlýtur að vera.
í can take:
- dative for location (being somewhere)
- accusative for motion into/into a place (movement toward a location)
Here it’s location (“is in”), so í takes dative: (í) geymslunni.
The base noun is geymsla; geymslunni is dative singular definite (“in the storage room”).
Yes:
- geymsla = “storage (room)”, feminine noun
- geymslu- = dative singular stem/ending
- -nni = the suffixed definite article in dative singular feminine
So geymslunni = “the storage room” specifically in the dative form required by í (location).
Because því is introducing an explanatory clause (“because/since …”). In Icelandic, it’s common to separate such clauses with a comma.
So the sentence is structured as main clause + comma + reason clause.
því can function in different ways depending on structure:
- As a conjunction meaning “because/since” (as here): ..., því ég setti...
- In the pattern því ... að ... (more formal) or in other uses where it relates to “therefore/for that reason” in meaning
In this sentence, the placement and clause after it make it clearly the “because/since” use.
setti is the past tense (preterite) 1st person singular of setja (“to put / to set”).
So ég setti = “I put (it)”.
Pronouns agree with grammatical gender in Icelandic. lykill is masculine, so “it” referring to the key is hann (masc.).
(For comparison: feminine “it” → hún, neuter “it” → það.)
It’s accusative because it’s the direct object of setti (“I put it”).
The nominative form would be hann as well for masculine? (Actually nominative masculine is hann, but in many pronouns nominative/accusative differ; here the key point is: after setja as a transitive verb, the object is in accusative, and hann is the correct object form for masculine “it/him”.)
þar means “there” and refers back to the previously mentioned place (í geymslunni). It’s very natural in Icelandic to restate the place with þar in the reason clause:
- Main clause: “The key must be in the storage room”
- Reason clause: “because I put it there yesterday”
It avoids repeating í geymslunni and makes the connection explicit.
Yes, time adverbials like í gær (“yesterday”) are flexible. Placing it at the end is very common and neutral.
You can also place it earlier for emphasis or flow, e.g. því ég setti hann í gær þar is possible but tends to sound less neutral; því ég setti hann þar í gær is a very typical order.
A few common learner points:
- þ (thorn) is like English th in thin: því
- ý is a long vowel (not like English “y”); hlýtur has a distinct long ý sound
- æ is a diphthong (similar to “eye” for many speakers): gær
- ll in Icelandic is often a special sound (can be “tl”-like in many contexts), so Lykillinn may not sound like an English “ll”
