When there are three strong root letters, the imperfect prefixes produce words with two closed syllables: יִזְ-כֹּר = he shall remember. Notice that since the first syllable is closed, the next letter gets a dagesh lene if it’s a בֶּגֶד כֶּפֶתletter. When suffixes are added, the second syllable reduces to a sh’va. When the first root letter is י or נ, that root letter will not be visible and a vowel change will compensate for the loss; final ה root letters will disappear when a suffix is added; when the middle root letter is ו or י, it may be represented by either a vowel letter or a simple vowel sign, and the vowel under the signal letter is kamatz. Otherwise, all three root letters are visible.
