"The flowers that we arranged for Teachers' Day have come."

[TharwatAk]

is it wrong to say "düzenlediğimiz çiçekler öğretmenler günü için geldi"?

[mizinamo]

That would be "The flowers that we arranged have come for Teachers' Day", I think.

Neden have come oldu bunu nasil anlayabiliriz came desek daha iyi olmaz mi

"The flowers have come" ve " "The flowers came" aynı anlama geliyor. "Have come" and "came" can both be used here. You could also say, "The flowers, that we arranged for Teachers' Day, arrived".
