differently with niqqud, the difference being segol and tzere. For example, עֶרֶב evening and עֵרֶב weft are both pronounced and written ערב without niqqud (these words also have different etymology). Writing tzere with and without matres lectionis Tzere can be written with and without matres lectionis. The most prominent mater lectionis for tzere is Yod (), and in some cases it is used with the letters aleph () and he (). Standard spelling rules mandate only one way to spell every word with or without the Yod after tzere. Although in standard modern pronunciation the sound of tzere with or without the Yod is the same, it may change the word's meaning in a written text (see below). Standard usage without Yod Tzere can be written by itself without mater lectionis, in which case it is called tzere ḥaser ("lacking tzere"), for example in the word (, wreath). In this case, in text without niqqud the vowel is usually not written at all: זר. This word can be also vocalized as (, stranger) and the reader has to guess the right pronunciation according to the context. According to the standardized Hebrew spelling the letter Yod is sometimes written in texts without niqqud, when there is a grammatical reason for it; for example, the verb (, she will be absent) is written without Yod in texts with niqqud, but the Yod is written in a text without niqqud: . Standard usage with Yod Tzere with Yod is called "full tzere". When a full tzere is written in text with niqqud, the letter Yod must be written in text without niqqud. The main cases for writing the tzere with Yod are these: Tzere is written with Yod to indicate the plural number of declined words, for example means our product and means our products; the standard pronunciation is the same: . Tzere is written with Yod in words in which the Yod is a part of the root: Nouns, for example בֵּיצָה (, egg), root ב־י־צ‎; זֵיתִים (, olives, the plural of זַיִת), root ז־י־ת‎, מֵידָע (, information), root י־ד־ע. Tzere is also traditionally written with Yod in several other words, the roots of which are rarely used productively to form other words, among them פְּסֵיפָס (, mosaic), קֵיסָם (, sliver) and the word "tzere" itself – צֵירֵי (). Verbs, in which the last letter of the root is he (ל״ה), which
