Þú getur hringt í mig hvenær sem er í kvöld.

A natural breakdown is:

• Þú = you
• getur = can / are able to
• hringt = call (from the verb hringja)
• í mig = me after the verb hringja í
• hvenær sem er = anytime / whenever
• í kvöld = tonight / this evening

So the structure is basically:

subject + can + call + me + anytime + tonight

Because after geta (can, be able to), Icelandic normally uses the form called the supine (sagnbót), not the infinitive.

So you get:

• geta hringt = can call
• geta komið = can come
• geta farið = can go

The dictionary form is hringja, but after geta the form becomes hringt.

A useful comparison:

• Ég vil hringja = I want to call
• Ég get hringt = I can call

So this is a real grammar pattern you will see a lot.

The dictionary form is geta.

In this sentence, getur is the 2nd person singular present tense, agreeing with þú:

• ég get = I can
• þú getur = you can
• hann/hún/það getur = he/she/it can

So Þú getur simply means you can.

The verb hringja meaning to call/phone someone is used idiomatically as hringja í einhvern.

So:

• hringja í mig = call me
• hringja í þig = call you
• hringja í hana = call her

English does not need a preposition here, but Icelandic does. You should learn it as a chunk:

hringja í + accusative person

Without í, it would not sound right for the meaning phone/call someone.

Because mig is the accusative form of ég (I / me), and the expression hringja í einhvern takes the accusative.

The forms are:

• ég = I
• mig = me

So:

• í mig = me, after í in this expression

It is not mér, because this verb pattern does not use the dative here.

It means anytime or whenever.

Literally, it is built from:

• hvenær = when
• sem er = a fixed pattern that gives the sense of -ever / any ... at all

So hvenær sem er is basically whenever or at any time.

You will see the same pattern with other question words:

• hver sem er = anyone
• hvað sem er = anything
• hvar sem er = anywhere

So this is a very useful expression pattern in Icelandic.

Here, er is part of the fixed expression sem er.

On its own, er is the present tense of vera (to be), but in combinations like hvenær sem er, you do not translate it word for word. The whole expression functions as one unit meaning whenever / anytime.

So it is best to learn hvenær sem er as a set phrase.

Í kvöld means tonight or this evening.

It usually refers to the evening part of the day. By contrast:

• í kvöld = tonight / this evening
• í nótt = tonight at night / during the night

So if you mean call me later this evening, í kvöld is the natural choice.

Also, í kvöld is a fixed time expression, so you should just learn it as a whole phrase.

Like English can, getur can cover more than one idea depending on context.

In this sentence, it does not have to mean literal ability only. It can sound like:

• You can call me tonight
• Feel free to call me tonight
• It’s fine if you call me tonight

So it often works as a friendly invitation or permission, not just physical ability.

If you wanted to stress permission more directly, Icelandic could also use mátt:

• Þú mátt hringja í mig í kvöld. = You may call me tonight.

But getur is very natural here.

Yes. Icelandic word order is flexible, especially with time expressions.

The original sentence is completely natural:

Þú getur hringt í mig hvenær sem er í kvöld.

But you could also say:

• Þú getur hringt í mig í kvöld hvenær sem er.
• Í kvöld geturðu hringt í mig hvenær sem er.

The meaning stays very close, but the emphasis shifts a little.

A useful rule: if you move something to the front in Icelandic, the finite verb still usually comes in second position.

Yes, þú is natural and normally kept. Icelandic usually does not drop subject pronouns the way Spanish or Italian often does.

So:

• Þú getur hringt ... = normal, clear Icelandic

As for formality: modern Icelandic usually just uses þú in everyday speech, even in many polite situations. There is no common everyday formal you equivalent like French vous or German Sie.

No. Hringja can also mean to ring.

For example, depending on context it can refer to:

• a phone ringing
• a bell ringing
• calling someone on the phone

But in the pattern hringja í einhvern, it specifically means to call/phone someone.

So in this sentence, the meaning is clearly call me, not ring me in a literal sense.

Þ is pronounced like the th in thing, not like the th in this.

And ú sounds like oo in food.

So Þú is roughly:

thoo

That letter Þ/þ is called thorn, and it is very common in Icelandic.
