דַּחְקוּת (dakhkut) — laughter (slang)
Etymology
The word דַּחְקוּת is the youngest branch of one of the oldest documented word families in human language — a family that goes back to the first speakers of Proto-Semitic thousands of years ago.
Linguists reconstruct a Proto-Semitic root ḍ.ḥ.k (requiring Latin-script representation because Proto-Semitic had 29 consonants while Hebrew has only 22 letters). The ḍ represents an emphatic sound that has been lost in Hebrew but preserved in Arabic as the letter ḍāl (a forceful, pharyngealized version of /d/). The ḥ is a pharyngeal /h/ (the "deep" ḥet of Yemenite speakers). The k represents both modern kaf and qof.
This ancestral root spread as its speakers migrated. One group went south back into Africa, developing into Ethiopian Semitic languages; in Amharic the laugh word became saq. Another group went east, developing into Akkadian, the first Semitic language to be written; in their cuneiform inscriptions, laughter was ṣiāḥu. A northern group settled at the Syrian port city of Ugarit; in Ugaritic, the laugh root was ṣ.ḥ.q. The group that remained in the Levant split into: Arabic (ḍ.ḥ.k → ḍaḥka), which went south to the Arabian Peninsula; Aramaic; and Canaanite, from which Hebrew descends.
In Hebrew, the Proto-Semitic ḍ had to share the letter tsadi (צ) with another phoneme, since the Phoenician alphabet adopted by the Israelites had too few characters. This yielded the Hebrew root צ.ח.ק — the very name Yitzhak (Isaac) means "he will laugh," from Sarah's response when told she would bear a son: "God has made laughter (tskhok) for me; all who hear will laugh (yitzhak) for me" (Genesis 21:6). The root also appears in an alternative Biblical spelling with שׂ (sin), giving the broader range of meanings: to play, to amuse, to sing, and even to have sexual relations.
In Aramaic, which displaced Hebrew as the Jews' daily language after the Babylonian exile, the Proto-Semitic root underwent radical changes and split into two: ג.ח.ך (appearing in the Talmud as gikhukh, giggling or snickering: "Rabbi Yirmiyah almost caused Rabbi Zeira to gikhukh but he did not," Nidda 23a) and ח.ו.ך (as in the Talmudic Aramaic phrase khokha ve-itlula, mockery and ridicule — the source of modern Hebrew חִיּוּך, smile).
The modern revival of Hebrew drew these words from the sources and assigned them distinct meanings: צְחוֹק (laughter, not smile), חִיּוּך (smile, not laugh), גִּיחוּך (snickering, not play). The last word to join this family in Hebrew was דַּחְקוּת — a distortion of the Arabic ḍaḥka (laughter). It entered Israeli colloquial Hebrew as slang.
