Full E-Type Vowel
In addition to the three simple E-type vowels, there are two variations that you should be aware of: Both Tsere and Segol may have a Yod immediately following it (the Yod then functions not as a consonant, but as a vowel letter):
The "X" refers to any Hebrew letter (for example Aleph, Bet, and so on) and the rectangular box below the letter refers to a vowel mark location. When the letter Yod follows a letter with a Tsere or Segol, it functions not as a consonant, but as a vowel letter. This is called a "consonantal vowel" and the result is called a "full" vowel.
