"Men and women are different."
Translation:남자와 여자는 달라요.
I believe this is because it's a 르 irregular verb. In such a case, you take the stem (다르 in this case), change the 르 to either 라 or 러 depending on the last vowel of the previous character (last vowel is ㅏ therefore 르 changes to 라), and then you add a ㄹ before the 라/러. i.e. the ㄹ sound is doubled. (다 becomes 달 and therefore put the 2 together and you have 달라 as it's conjugation.)
