This acknowledged borrowing is from Arabic alkohl (powder of antimony). The Aramaic-Syriac (typically cumbersome)
equivalent is כוחלא KOOK[H]LAh.
The Akkadian is guhlu (antimony). As seen in Ezekiel 23:40, the Biblical
KoK[h]aL means he painted his eyelids with antimony (EDK). Even if כחל Kahf-Het-Lamed did not mean ALCOHOL, it is cited here as the
older, Edenic source of ALCOHOL.
The color of this antimony or eye makep is blue; כחל KaK[H]oaL became blue in Post-Biblical Hebrew. The Modern
Hebrew spelling of the Hebrew for alcohol uses a ה Hey, instead of the older ח Het. ח Het is like a guttural ה Hey, both graphically and audibly. (The
air-flow is closed off, forcing a harsher throat sound.)
חול K[H]OAL means sand mixed with clay.
Related earthy words are at COAL. Beyond chemistry, eye makeup
and alcohol can be an explosive mix. A related, reddish ר - ח Het-Resh or guttural-liquid clay word
is חרס [K]HeR e$, pottery (Jeremiah 19:2). See
CERAMIC. The red-brown of pottery is likely similar to the color of a
diseased liver, and why CIRRHOSIS is from Greek kirrhos (tawny-colored).
CIRRHOSIS has no Indo-European root. Kenneth H. Ryesky saw the color and
texture similarity in the Passover seders symbolic mortar: חרסת [K]HaRoSe(S). More clay color at MAROON.
Ezekiel 23:40 ואף כי תשׁלחנה לאנשׁים באים ממרחק אשׁר מלאך שׁלוח אליהם והנה־באו לאשׁר רחצת כחלת עיניך ועדית עדי׃
And furthermore ye have sent for men that come from far; unto whom a messenger was sent, and, lo, they came; for whom thou didst wash thyself, paint thine eyes, and deck thyself with ornaments;
