Questions & Answers about De här väggarna är bara två millimeter tjocka.

Why is it just två millimeter and not a plural form, since there are two of them?
In Swedish, units of measurement ending in -er (like millimeter, meter, and liter) usually do not change their form in the plural when they come right after a number. So you say en millimeter and två millimeter.
Does the adjective tjocka (thick) agree with the measurement or the walls?
It agrees with the noun being described, which is väggarna (the walls). Since väggarna is plural, the adjective takes the plural -a ending to become tjocka. The measurement två millimeter simply tells us how thick the walls are.
Why do we use the definite form väggarna after De här?
This is a quick refresher on the classic Swedish double definite rule. When using den här, det här, or de här (this/these), the noun that follows must be in its definite form. You literally say 'These here the-walls' (De här väggarna).
Is the word order for measurements identical to English here?
Yes, it works exactly the same way! You put the quantity (två millimeter) directly in front of the descriptive adjective (tjocka). You will use this exact pattern for other measurements in this lesson too, like två meter lång (two meters tall) or trettio år gammal (thirty years old).
