Learn Finnish: Tämä viihdyttävä jakso tuntuu lyhyeltä. - This entertaining episode feels short.

The verb tuntua (to feel) requires the adjective describing the feeling to be in the ablative case (-lta or -ltä). While you might hear the allative case (lyhyelle) in casual speech, lyhyeltä is the standard form for expressing that something 'feels short'.

Is viihdyttävä a standard adjective?

It functions as one, but it is actually the present active participle (often called the VA-participle) of the verb viihdyttää (to entertain). In Finnish, it is very common to use these participles exactly like adjectives, just as we use the word 'entertaining' in English.

How does the word lyhyt transform into lyhyeltä?

The word lyhyt (short) belongs to a specific group of words ending in -ut or -yt. To find the stem for adding case endings, the final -t drops out and the preceding vowel changes to an -e-, giving the stem lyhye-. Finally, the ablative ending -ltä is attached.
