|Unicode name||HEBREW LETTER HE|
- He, hei: the fifth letter of the Hebrew alphabet, after ד and before ו.
- The numeral 5 in Hebrew numbering.
Usage notes 
- The letter ה represents the traditional phoneme /h/ (like the sound of <h> in the English word hat). In present-day Israeli Hebrew, this phoneme is generally dropped in ordinary speech — a word such as הֵם (hém, “them”) is usually pronounced /em/, at least in everyday conversation — but the letter ה is still used where the sound /h/ would be expected, such as in loanwords where the source word has /h/.
- The letter ה is also used as a silent letter (a mater lectionis) at the end of a word, to indicate the presence of a vowel that is not otherwise indicated. This vowel is usually /a/ (as in יַלְדָּה (yaldá) and סֶלָה (séla)), but often /e/ (as in אֵלֶּה (éle) and תֵּה (té)), and in a few cases /o/ (as in כֹּה (kó)). However, final vowels are not necessarily indicated by any letter at all; for example, the words לְךָ (l'khá), אָמַרְתָּ (amárta), and אֵלֶיהָ (eléha) all end with a vowel /a/ that is not indicated by a following letter. Conversely, this silent use of ה appears, in a very small number of exceptional cases, in the interior of a word, such as in יְפֵהפֶה (y'fefé).
- In writing with vowels, when a letter ה representing the phoneme /h/ occurs at the end of a word, it is written with dot inside, called a mapík, to distinguish it from the silent use: לָהּ (láh), גובה \ גֹּבַהּ (góvah).
- Like the letters א, ח, ע, and ר, the letter ה never takes a dagésh (that is: in traditional Hebrew, which distinguished consonant length, the phoneme /h/ never underwent gemination), and in circumstances where a dagésh would otherwise be expected, there is frequently a change in the preceding vowel. For example, the infinitive of נֶהֱרַג (neherág) is לְהֵהָרֵג (l'heiharég) rather than *לְהִהָּרֵג (l'hiharég).
- Like the letters א, ח, and ע, the letter ה generally does not take a sh'vá (be it a sh'vá ná or a sh'vá nákh); rather, it takes a khatáf vowel: הֲלִיכָה (halikhá), נֶהֱרַס (neherás), צהריים \ צָהֳרָיִם (tsohoráyim). Additionally, like word-final ח and ע, a word-final non-silent ה takes a patákh g'nuvá after any vowel other than /a/: גבוה \ גָּבֹהַּ (gavóah).
- Since ה is used as a silent letter at the end of a word, it also is traditionally used as a placeholder in the representation of consonantal roots that have a sort of “gap” at the end. For example, the roots of the verbs קָנָה (kaná), נִרְאָה (nir'á), הִרְשָׁה (hirshá), חיכה \ חִכָּה (khiká), and הִתְגַּלָּה (hitgalá) are ק־נ־ה (k-n-), ר־א־ה (r-'-), ר־שׁ־ה (r-sh-), ח־כ־ה (kh-k-), and ג־ל־ה (g-l-), respectively. In some forms, this “gap” becomes ת /t/ (as in קָנְתָה (kan'tá)); in others, it becomes י /j/ (as in גילוי \ גִּלּוּי (gilúi)); in others, it becomes a silent א (as in הַרְשָׁאָה (harsha'á)); and in others, it essentially disappears (as in נִרְאוֹת (nir'ót)).
