Questions & Answers about Minun täytyy leikkauttaa tukka.
How is the verb leikkauttaa formed from leikata?
It is built from the strong vowel stem of leikata, which is leikkaa-. When you add the curative suffix -uttaa, one 'a' at the end of the stem is dropped, resulting in leikkauttaa. This suffix shows that you are having someone else perform the action.
How would the meaning change if I said Minun täytyy leikata tukka instead?
If you used the base verb leikata, it would mean you are going to cut your own hair. The curative verb leikkauttaa specifies that you are commissioning someone else, like a hairdresser, to do it for you.
Why is the object tukka in the nominative case rather than the genitive (tukan)?
This is an important rule for necessity verbs like täytyy. When you use a necessity structure, a total object (representing the whole thing being acted upon) must be in the nominative case (tukka) instead of the normal genitive case.
Why is the word minä in the genitive form minun?
The verb täytyy always requires its subject to be in the genitive case. This necessity structure translates roughly to 'It is necessary for me', so the 'for me' part acts as the grammatical subject in Finnish.
