"Det er en stor hvid strand."

Translation: It is a big white beach.

[sam.cn21]

I wrote "It is a big white strand", but it is wrong! we have "strand" which means "beach" in English as well

[markopolo14]

Doesn't strand also mean shore(or is it shoar?)

[DaneTR]

There exisists nothing called "shoar". "shore", on the other hand, would be "kyst" or perhaps "bred".

[ZedString]

this sentence refers to Cancún btw.

[SantiAnnd]

It is a big white a$$.

[Fred-3-CMY]

Is there any rule when an "A" is pronounced like an "a" as in Danish (or German) "strand" and when it is pronounced as an "open e" such as in "han"?

There are at least two groups:
a) strand, aften, langt, bank
b) han, mand, kalde, dansk,
and even a third one:
c) stadig, dag, bade

Seems rather arbitrary when an "A" is pronounced how...
