Questions & Answers about Pisin dinosaurus oli myös suurin.
Why is the word for "longest" pisin? What is the base word?
Pisin is the superlative form of pitkä (long). This is a highly irregular word in Finnish. Just like how "good" completely changes to "best" in English, the root of pitkä changes to pis- before adding the superlative ending -in.
How do we form suurin (largest) from suuri (large)?
The adjective suuri has the vowel stem suure-. The basic marker for the superlative is -in. When you attach -in to the stem suure-, the final e drops out, leaving you with suurin.
Both pisin and suurin end in -in. Is that the standard superlative ending?
Yes, -in is the standard ending for the superlative in the basic dictionary form (nominative case). However, if you need to put these words into other grammatical cases (like saying "in the largest"), that -in will change into the stem -imma- or -impa-.
Since superlatives are used, why isn't the partitive case used anywhere in this sentence?
