Learn Swedish: Du kan animera dinosaurien hur snabbt som helst. - You can animate the dinosaur as fast as you like.

The structure hur [adverb/adjective] som helst literally translates to "how [fast] as rather". In Swedish, this set phrase is used to express an extreme or unlimited degree of something. It means that there is no upper limit, translating smoothly to "as fast as you want", "as fast as possible", or even "incredibly fast".

Why is the word snabbt used here instead of snabb?

Here, snabbt functions as an adverb describing the verb animera (how you animate), rather than an adjective describing a noun. To form an adverb in Swedish, you generally add a -t to the base form, similar to adding "-ly" in English.

Why does the definite word dinosaurien only take an -n suffix instead of -en?

The base word for dinosaur is dinosaurie, which is an en-word that already ends in a vowel. To make it definite (the dinosaur), you only add -n rather than the full -en ending to avoid an awkward double-vowel sound.

Can this hur ... som helst construction be used with other adverbs or adjectives?

Yes, this is a very common and productive pattern in Swedish. You can swap in almost any adjective or adverb to intensify it. For example, hur stor som helst means "as big as you want" or "infinitely big", and hur lätt som helst means "as easy as can be".
