Not good to use the letter e in this transliteration; e means the vowel in "bed." Instead you use i. (You will sometimes people see people use ee to show it's the longer sound like the i in machine or Lisa.) It's also good to show the accented syllable, especially if it is not the last syllable (which is most common in Hebrew). On my smartphone I write capital letters to show the accent: sliKhA or sliKHA.
סליחה , את בסדר ? my translation : Excuse me are you fine? Duolingo transalation : Are you ok ? in english langauage ok is actually slang. so is my translation incorrect ?
