Questions & Answers about Poika ottaa keittoa.
Why is it keittoa instead of just keitto?
Keitto means soup, which is a mass noun (a substance you cannot easily count). Because the boy is taking an unspecified amount of it (some soup) rather than all the soup in existence, it acts as an indefinite object. In Finnish, we add the partitive ending -a to show this indefinite amount.
The English translation says some soup, but there is no separate word for some in the Finnish sentence. Where is it?
Finnish rarely uses a separate word for some. Instead, the idea of some is built right into the word keittoa through the partitive ending -a.
I learned earlier that I take is otan with only one t. Why does ottaa have two?
This happens because of a pattern called consonant gradation. The dictionary form is ottaa (strong grade, two t's). The he/she/it form also uses the strong grade, so poika ottaa keeps both t's. However, forms like I (otan) and you (otat) use the weak grade, which drops one t.
If the soup gets a special ending, why does poika stay in its basic form?
Poika is the subject of the sentence (the person doing the action). In basic sentences like this, the subject stays in the nominative case, which is simply the plain dictionary form with no extra endings.
