Definition from Wiktionary, the free dictionary
- Like other words that start with ב, ג, ד, כ, פ, or ת, this term's initial letter takes a dagesh lene. In older texts, that dagesh is usually dropped when the word is preceded, in the same phrase, by a word ending in a mater lectionis; in modern texts, the dagesh is usually preserved even in such a case. Likewise, in older texts, the dagesh is always dropped when the word is prefixed by an indefinite ב־, כ־, or ל־, or by ו־; in modern speech, the dagesh is often preserved in such a case. (After the definite ב־, כ־, and ל־, and after the prefixes ה־, מ־, and ש־, there is a dagesh forte, as described in the usage notes for those prefixes.)
- This noun is feminine in the Bible, but is masculine in the Mishnah and in later writings, even to modern times. When Hebrew was reinvented as a spoken language, though, the word reverted to feminine, as in the Bible.
