Learn Swedish: Jag tycker om hunden och katten.

Tycker belongs to Group 2 of regular Swedish verbs. To make the present tense for this group, you drop the final -a from the dictionary form (tycka) and add -er. This gives us tycker for things happening right now or in general.

What does the word om do in this sentence?

On its own, om usually translates to 'about' or 'if'. But when combined with the verb tycker, it creates a fixed phrase that means 'to like'. If you just said Jag tycker, it would mean 'I think' or 'I have the opinion that'. You need the om to express that you like something.

Why are there no separate words for 'the' before the dog and the cat?

In Swedish, 'the' is usually not a separate word before the noun. Instead, it is attached to the end of the word as a suffix. Because hund (dog) and katt (cat) are both 'en-words', you add -en to their ends to make them definite: hunden means 'the dog' and katten means 'the cat'.

Is there another way to say 'like' in Swedish?
