Questions & Answers about Minä olen piirtänyt tuon kuvan.
How is the word piirtänyt formed here?
The dictionary form is piirtää (to draw), which is a Type 1 verb. To form the active past participle (the "-ed" or "-en" part of "have drawn"), you take the stem piirtä- and add -nut or -nyt. Because of vowel harmony (the word contains the front vowel ä), we use -nyt, making it piirtänyt.
Wait, why isn't there consonant gradation in piirtänyt? Doesn't the rt usually change to rr?
That is a great catch! While the present tense uses the weak grade (minä piirrän = I draw), the active past participle for Type 1 verbs always uses the strong grade. The strong consonants stay intact, which is why it remains piirtänyt.
How does the perfect tense ("have drawn") work in this sentence?
Just like in English, the perfect tense uses a helper verb plus a past participle form of the main verb. However, in Finnish, the helper verb is olla (to be) instead of "to have". So, olen (I am) + piirtänyt (drawn) creates the meaning "I have drawn".
Why do both tuo and kuva end in -n (tuon kuvan)?
