Questions & Answers about Yritän estää sinua tuhlaamasta rahaa.
Why is the verb for wasting in the form tuhlaamasta?
The verb estää (to prevent) is a verb of prevention. It requires the action being prevented to be expressed in the 3rd infinitive elative form, which ends in -masta or -mästä. Here, the verb tuhlata (to waste) becomes tuhlaamasta. This works very much like the English structure of preventing someone 'from doing' something.
Why is the word for you (sinua) in the partitive case?
The verb estää takes a partitive object for the person or thing being stopped. Because preventing someone is treated as an ongoing or incomplete action in Finnish grammar, the basic pronoun sinä becomes the partitive sinua.
How do we form tuhlaamasta from the dictionary verb tuhlata?
The verb tuhlata is a type 4 verb. To build the 3rd infinitive, you take the vowel stem used in the third-person present tense (hän tuhlaa), and add the elative ending -masta to get tuhlaamasta.
