Ég ætla að fara til Íslands í desember með manninn minn. Við förum fyrst í Reykjavík og ætlum að fara á söfn og á sundlaugar þarna. Næstur, við ætlum að leiga bíl. Ég vil fara á Bláa Lónið* og sjá Þingvelli. Það er kalt í desember í Íslandi en það er kaldari í Minnesota.
*Today's grammar point which ended up being a lot longer than the actual post...no surprises there tbh. Okay so Bláa is the correct version according to Wikipedia & it's the weak declension's neuter nominative (and accusative) form. But why are we using the weak declension here at all? The weak declension is used when the definite article is being added and it is actually really easy. Here's another link on adjectives, which I am going to shamelessly copy & paste below:
Adjectives take weak endings when,
1.) they are used with a definite noun
2.) with a demonstrative pronoun (i.e., this, that)
Adjectives take strong endings when,
1.) they are used with an indefinite noun
2.) after the verb að vera - to be
So The Blue Lagoon is Bláa Lónið, but a blue lagoon would be blátt lón. Similarly, enski maðurinn but enskur maður, and stóra búðin but stór búð.
Ég fer á gamla safnið - I go to the old museum
Ég fer á gamalt safn - I go to an old museum
Þessi japanska ryksuga er ódýr - This Japanese vacuum cleaner is cheap
Þessi ódýra ryksuga er japönsk - This cheap vacuum cleaner is Japanese
^Note that in this example, both the adjectives agree in gender with ryksuga (f), but the first position uses the weak declension (comes after a demonstrative pronoun) while the second position uses the strong declension (comes after að vera).
I think I have this right, but if there are any mistakes anywhere, please correct me!
