"She is walking on the beach in autumn."
Translation:Sonbaharda kumsalda yürüyor.
scission, i find the lesson you remember: the learner's question was: "Can I say, "Yazda etek giyerim."? AlexinNotTurkey's answer was: "Nope, "yaz" is an irregular word. To say "in the summer" you would say "yazın". If you tape "yazın" in duolingo sentences, you find the lesson with the comments. Very usefull.
