מְזֻיָּן (Mezuyan) — armed / fucked

Etymology

The journey of mezuyan begins with the Old Persian word for weapon, zaēna. Following Cyrus the Great's conquest of the Ancient Near East in 539 BCE, the word was adopted into Aramaic—the administrative language of the Persian Empire—as zayin. It eventually entered Hebrew during the Talmudic period, appearing in the Tosefta and other Rabbinic literature to describe weapons and the act of arming oneself.

During the Talmudic era, the word also gained a secondary meaning related to "decoration" or "beauty" under the influence of the Arabic root z-y-n (as in zinah, decoration). This usage is famously preserved in the "crowns" (ziyunin) placed atop certain Hebrew letters in a Torah scroll. In the late 19th century, Eliezer Ben-Yehuda attempted to repurpose the word ziyun to mean "risk," based on an Aramaic legal term for financial loss, but the public ultimately preferred the term sikun.

In the early 20th century, a dramatic semantic shift occurred. Students at the Herzliya Gymnasium in Tel Aviv began using zayin (the name of the seventh letter) as a euphemism for the penis, possibly due to its shape or as a shorthand for other vulgarities. From this, the verb lezayen (to fuck/to cheat) and the adjective mezuyan (fucked/cheated) entered Hebrew slang. By 1937, engineers were already reporting this "corrupted" usage to the Hebrew Language Committee.

This linguistic evolution created a sharp divide between the older generation, who used the word in a military context, and the younger generation, for whom it was strictly vulgar. A famous anecdote from the 1950s describes Menachem Begin giving a fiery speech about world powers "arming" (mezaynim) Nasser, which led to uncontrollable laughter from a young Amos Oz. Today, the military meaning has largely been replaced by the word chamush, though mezuyan survives in fixed idioms like "armed robbery" (shod mezuyan) and "reinforced concrete" (beton mezuyan).
