Gløderne er varme.

It has a very common Danish sentence pattern:

• Gløderne = the subject
• er = the verb, present tense of at være
• varme = an adjective describing the subject

So grammatically it is:

subject + verb + adjective

This is the same basic pattern as English The embers are warm.

Because Danish often puts the definite article on the end of the noun instead of using a separate word before it.

So:

• gløder = embers
• gløderne = the embers

The ending -ne is the definite plural ending here.

A useful comparison:

• en glød = an ember
• gløden = the ember
• gløder = embers
• gløderne = the embers

The dictionary form is en glød.

Its forms are:

• en glød = an ember
• gløden = the ember
• gløder = embers
• gløderne = the embers

So gløderne is the definite plural form.

Because the subject is plural.

In Danish, adjectives often change form depending on what they describe:

• varm = used with a singular en-word
• varmt = used with a singular et-word
• varme = used with plurals

So:

• En glød er varm = An ember is warm
• Et gulv er varmt = A floor is warm
• Gløderne er varme = The embers are warm

Yes.

Er is the present tense of at være, and Danish does not change it for singular and plural the way English does.

So both of these are correct:

• Gløden er varm = The ember is warm
• Gløderne er varme = The embers are warm

In both sentences, the verb is still er.

Very roughly, you can think of it as something like GLØ-thər-nuh, with the stress on the first syllable.

A few important points:

• g is pronounced like the g in go
• ø has no exact English equivalent; try making an e/uh-type sound with rounded lips
• the d in gløderne is usually soft, not a hard English d
• -ne at the end is a weak ending, roughly like nuh

The hardest sound for most English speakers is ø.

It can often cover both, depending on context.

Danish varm / varme has a wider range than English warm sometimes does. In some contexts, English might naturally choose hot instead.

So with embers, English often says hot, but Danish can still use varme.

If you want a stronger idea of hot, Danish also has hed.

Yes.

Glød can refer to:

• a literal glowing ember
• a glow
• sometimes a figurative glow or intensity

But in Gløderne er varme, the most natural meaning is physical embers or glowing coals.

Yes, but this sentence uses the most straightforward order.

Here it is:

Gløderne er varme = subject first, then verb

Danish main clauses follow the verb-second rule, so if something else comes first, the verb still stays in second position:

• Nu er gløderne varme = Now the embers are warm
• I pejsen er gløderne varme = In the fireplace, the embers are warm

But in a normal simple statement, Gløderne er varme is exactly what you would expect.

Then Danish usually uses a separate definite word before the adjective, instead of the noun ending -ne.

So compare:

• Gløderne er varme = The embers are warm
• de varme gløder = the warm embers

Notice the difference:

• after the verb: gløderne
• before the noun with an adjective: de varme gløder

That pattern is very common in Danish.
