Learn Swedish: Förtroendet och stödet är lika viktiga som kärleken. - Trust and support are as important as love.

In Swedish, when you talk about an abstract concept in a general, universal sense, you usually use the definite form (adding the -et or -en ending). In English, we leave these nouns indefinite, but Swedish prefers "the love" (kärleken) to talk about love as a whole concept.

Why is it viktiga rather than viktig or viktigt?

Because it describes two things: förtroendet and stödet. Together they form a plural subject, so the adjective takes the plural -a ending.

How does the lika ... som structure work here?

This is the standard way to express that two things are equal. You put lika (equally) before the adjective and som (as) after it. So lika viktiga som translates literally to "equally important as".

How would I use the current lesson's focus word, varandras (each other's), to talk about "each other's support"?
