Questions & Answers about Sinun syötteesi passivoitui, sillä et päivittänyt sitä.
How is the verb passivoitui formed, and what does the suffix do here?
It comes from the adjective passiivinen (passive) or the noun passiivi. By replacing the ending with the suffix -oitua, it forms an automative verb describing a natural process or change of state. So passivoitua means 'to become passive' or 'to deactivate itself'. Here it is in the past tense, meaning it 'became passive'.
Why does the word syöte (feed or input) change to syötteesi in this sentence?
The noun syöte ends in -e. To form its stem, you double the final vowel and apply reverse consonant gradation (adding the double -tt-), resulting in the stem syöttee-. Finally, the possessive suffix -si (your) is attached. The pronoun sinun before it is optional but adds emphasis.
Why is the word for 'it' (se) in the partitive form sitä?
Because the verb phrase is negative (et päivittänyt, meaning 'you did not update'). In Finnish, the direct object of a negative sentence must always take the partitive case, regardless of what case it would take if the sentence were positive.
Could I use koska instead of sillä in this sentence?
Yes, you can. Both words mean 'because' or 'for'. Sillä is a conjunction that sounds slightly more formal or written, often translated as 'for', whereas koska is the more common everyday word for 'because'.
