Questions & Answers about Du kan känna dig trygg så länge som du minns larmkoden.
Is the word som strictly necessary in så länge som?
No, the word som is optional. You can say så länge du minns larmkoden or så länge som du minns larmkoden. Both mean precisely the same thing and work just as well for this conditional phrase.
Why do we need the reflexive pronoun dig after känna?
In Swedish, to express how you feel inside (your physical or emotional state), you must use the reflexive verb känna sig. If you drop dig, the verb känna would mean to physically touch something or to know someone.
Could I use säker instead of trygg to mean safe?
You could, but trygg is the most natural choice here. Trygg refers to a subjective feeling of safety, comfort, and peace of mind. Säker usually refers to objective, physical security (like a secure building) or being certain about a fact.
Why does the verb minns end in an s, and where is the present tense r?
The verb minnas (to remember) is a deponent verb, meaning it always ends in an s in all its forms but has an active meaning. In the present tense, its form is just minns rather than adding an r before the s.
