I'm starting to learn that in Finnish the articles like 'the' and 'a' are implied in the nouns themselves. I always wondered why they seem to use less words in their sentences than we would use in English.
Finnish just doesn't have concept of definitiveness. So articles are omitted as useless. However prepositions like at, by, in, on, to, from... are implied with endings in nouns, adjectives, pronouns and numerals.
