Konsertti oli loppuunmyyty, joten odotimme pitkään ulkona.

Loppuunmyyty means sold out.

It is a compound made from:

• loppuun = to the end / completely
• myyty = sold (the past participle of myydä, to sell)

So the literal idea is something like sold to the end, meaning there are no tickets left.

In Finnish, this kind of compound is very common. Instead of using a separate phrase like English sold out, Finnish often packs the meaning into one word.

Oli is the past tense of olla (to be).

• on = is
• oli = was

So:

• Konsertti on loppuunmyyty = The concert is sold out
• Konsertti oli loppuunmyyty = The concert was sold out

Since the whole sentence describes a past situation, Finnish uses the past tense here.

Because Finnish verbs usually already show the subject.

Odotimme means we waited. The ending -imme tells you the subject is we.

So Finnish often leaves out the pronoun me (we) unless it is needed for emphasis or clarity.

Compare:

• odotin = I waited
• odotit = you waited
• odotti = he/she/it waited
• odotimme = we waited
• odotitte = you all waited
• odottivat = they waited

So in this sentence, me is unnecessary because odotimme already includes that meaning.

The dictionary form is odottaa = to wait.

To make we waited, Finnish uses the past tense stem plus the personal ending:

• odottaa → stem odotti-
• add -mme for we
• result: odotimme

So odotimme = we waited.

This is a normal Finnish past tense pattern. The double tt in odottaa becomes t in some forms because of consonant gradation:

• odottaa
• odotan
• odotimme

This kind of stem change is something learners see often in Finnish verbs.

Pitkään is an adverb meaning for a long time.

It comes from pitkä (long), but here it is not an adjective describing a noun. Instead, it describes the action odotimme (we waited), so Finnish uses the adverbial form pitkään.

Examples:

• Odotimme pitkään. = We waited a long time.
• Hän nukkui pitkään. = He/She slept for a long time.

This is not the same as pitkä, which would describe a noun:

• pitkä jono = a long queue

So:

• pitkä = long (adjective)
• pitkään = for a long time / at length (adverb)

Because ulkona means outside in the sense of being located outside, while ulos means out / to the outside in the sense of movement.

In this sentence, the people were waiting outside, so it is a location, not a direction.

• ulkona = outside (where?)
• ulos = out / outside (to where?)

Compare:

• Odotimme ulkona. = We waited outside.
• Menimme ulos. = We went outside.

A useful pattern:

• Missä? (Where?) → ulkona
• Mihin? (To where?) → ulos

Joten means so, therefore, or thus.

It connects the two parts of the sentence:

• Konsertti oli loppuunmyyty = The concert was sold out
• joten odotimme pitkään ulkona = so we waited outside for a long time

It shows a result or consequence.

Similar words include:

• joten = so / therefore
• siksi = therefore / for that reason
• niin = so

In this sentence, joten is a very natural way to link cause and result.

Because joten introduces a new clause, and in Finnish it is normally preceded by a comma.

So the sentence is divided into two parts:

• Konsertti oli loppuunmyyty,
• joten odotimme pitkään ulkona.

This is similar to English, where you often put a comma before so when it joins two full clauses.

No, this is a very normal and neutral Finnish word order.

• Konsertti = subject
• oli = verb
• loppuunmyyty = predicate
• joten = connector
• odotimme = verb
• pitkään = adverb of duration
• ulkona = adverb of location

So the sentence is straightforward and natural.

Finnish word order is more flexible than English, but this version sounds neutral and standard. You could move some parts for emphasis, but the original is the most ordinary way to say it.

Yes, it functions like an adjective in the sentence, even though it comes from a participle.

In Konsertti oli loppuunmyyty, the structure is:

• Konsertti = subject
• oli = was
• loppuunmyyty = sold out

This is similar to English The concert was sold out, where sold out behaves like a description of the concert.

So in practice, you can think of loppuunmyyty here as a predicate adjective meaning the state of the concert.

Yes, absolutely.

Me odotimme pitkään ulkona also means We waited outside for a long time.

But in ordinary Finnish, the pronoun me is often omitted because odotimme already tells you the subject is we.

Including me can add emphasis, contrast, or clarity:

• Odotimme pitkään ulkona. = neutral
• Me odotimme pitkään ulkona. = we waited outside for a long time

So both are correct, but the version without me is very natural.
