Questions & Answers about Ha spento tutti i monitor due ore fa.
Why does monitor not have a plural ending like monitori?
What is the infinitive of spento?
It comes from spegnere, which means to turn off or to extinguish. It has a highly irregular past participle. A helpful pattern to remember is that several verbs ending in -gnere have past participles ending in -nto, just like spegnere becomes spento and piangere becomes pianto.
Why is there an i right after tutti?
How do we know it was a he who turned off the monitors?
We actually do not know for sure just from this sentence! Italian drops subject pronouns most of the time. The verb ha tells us it is the third-person singular, so it could translate to he turned off, she turned off, or even the formal you turned off. The English translation just provides one likely option.
