Questions & Answers about Vaimo auttaa teitä aina.
Why is "you" translated as teitä instead of te?
The verb auttaa (to help) requires its object to be in the partitive case. Since the wife is helping "you", the basic pronoun te changes to its partitive form, teitä.
Does teitä mean "you" as in multiple people, or just one person?
It can be both! Te (and its partitive form teitä) is the plural "you" addressing multiple people. However, Finnish also uses it as a polite, formal way to address a single person.
In English we say "always helps", but here aina is at the end. Can I put it before the verb?
In Finnish, adverbs like aina (always) usually come after the verb, not before it like in English. Saying Vaimo auttaa teitä aina or Vaimo auttaa aina teitä sounds natural, but putting aina before the verb would sound unnatural to a Finnish speaker.
How do we know vaimo means "The wife" and not "A wife"?
Finnish doesn't have words for "a" or "the" (articles). Whether vaimo means "a wife" or "the wife" depends entirely on the context. In a standalone sentence like this, we usually assume the definite "the".
