Bindningstiden och uppsägningstiden är långa.

Because Swedish makes compound nouns very freely, and they are normally written as one word.

So:

• bindningstid = bindning
  • tid
• uppsägningstid = uppsägning
  • tid

Then -en is added at the end to make each noun definite:

• bindningstid + en → bindningstiden
• uppsägningstid + en → uppsägningstiden

English often uses separate words where Swedish prefers one compound word.

A useful breakdown is:

• bindning = binding, commitment, being tied in
• tid = time, period
  → bindningstid = a binding period or lock-in period

And:

• uppsägning = cancellation, termination, giving notice
• tid = time, period
  → uppsägningstid = a notice period or termination notice period

So the sentence is talking about two different kinds of contract-related periods.

Because -en is the definite article suffix here, meaning the.

In Swedish, instead of putting a separate word before the noun, you often attach definiteness to the end of the noun:

• bindningstid = binding period

• bindningstiden = the binding period

• uppsägningstid = notice period
• uppsägningstiden = the notice period

Both nouns are singular and definite.

Because Swedish usually marks definiteness by adding a suffix to the noun.

So English:

• the binding period
• the notice period

becomes Swedish:

• bindningstiden
• uppsägningstiden

This is completely normal Swedish. A separate article like den is not used here.

Because each noun refers to one specific period:

• the binding period
• the notice period

There are two items total, but each item is singular. This works the same way in English:

• The binding period and the notice period are long.

So Swedish uses two singular definite nouns joined by och, and together they make a plural subject.

Because the subject is plural overall: it contains two nouns joined by och.

The adjective lång changes form depending on number and gender:

• lång = singular, common gender
• långt = singular, neuter
• långa = plural

Since bindningstiden och uppsägningstiden means the binding period and the notice period, the whole subject is plural, so Swedish uses långa.

A few comparisons:

• Bindningstiden är lång. = The binding period is long.
• Avtalet är långt. = The contract is long.
• Bindningstiden och uppsägningstiden är långa. = The binding period and the notice period are long.

Because Swedish verbs do not change for singular and plural the way English verbs sometimes do.

The verb är is the present tense of vara = to be, and it stays the same with all subjects:

• Jag är
• du är
• han är
• vi är
• de är

So är works for both:

• Bindningstiden är lång.
• Bindningstiden och uppsägningstiden är långa.

Yes. Very much so.

The verb säga upp means things like:

• to cancel
• to terminate
• to give notice
• sometimes to dismiss or to resign, depending on context

From that verb you get the noun uppsägning, meaning:

• cancellation
• termination
• notice

So uppsägningstid is literally something like termination/notice period.

This is a very common pattern in Swedish: a verb or verbal expression gives rise to a noun, which then becomes part of a compound.

Yes, it sounds natural, especially in contexts involving:

• phone contracts
• internet subscriptions
• gym memberships
• rental agreements
• employment contracts

The sentence has a slightly formal or explanatory feel, which fits contract language well.

A common variation is:

• Både bindningstiden och uppsägningstiden är långa.

Adding både means both, and gives a little extra emphasis:

• Both the binding period and the notice period are long.
