Questions & Answers about Är du säker på alibit?
Why is på used instead of om for "about"?
Certain adjectives in Swedish are always followed by specific prepositions, and they don't always match the English translation. The adjective säker (sure/certain) pairs with på. So, "sure about" or "sure of" is always säker på.
Why is "the alibi" written as alibit?
Alibi is an ett word (ett alibi). When an ett word ends in a vowel, you simply add -t to the end to make it definite ("the"). Therefore, alibi becomes alibit.
Would säker change if I were asking a group of people?
Yes. Because du (you, singular) refers to one person, we use the basic form säker. If you were asking a group using ni (you, plural), the adjective must take the plural -a ending: Är ni säkra på alibit?
