Do I need the "ja" in this sentence? Sometimes the right answers don't use it.
No, you do not.
What does "tvé stroje slyšíš" translate to? "We see your machines"?
Slyšíš would be "you hear" or "you can hear" (singular). The course accepts translations with and without "can" for sensing verbs like this.
I see! I meant to type out "hear", not "see", but thank you for the answer!
why not 'tvuj stroje slysim'?
Tvůj is singular, while stroje is plural.
Ahaa, yes! Tvoje was suitable for singular and plural, but tvuj not, i remember. Dekuji :)
