I'm on lesson 15, and have a question about the vowels in the feminine plural pronoun for "you". The HB101 video, Dr. Futato's textbook, and the HB101 vocabulary cards show a tsere (two dots) as the second vowel. The HB101 transcript, HB101 activities, and the Mansoor textbook show a segol (three dots) as the second vowel. Are both forms correct? The inconsistency is confusing.
