נֶכֶד / נִין / אַחְיָן (nekhed / nin / akhyan) — grandchild / descendant / nephew or niece

Etymology

Modern Hebrew uses נֶכֶד for "grandchild" and נִין for "great-grandchild." These assignments are not biblical: in the Ten Commandments (Exodus 20:5; Deuteronomy 5:9), God visits iniquity upon בָּנִים, שִׁלֵּשִׁים (third generation), and רִבֵּעִים (fourth generation). The biblical words נֶכֶד and נִין appear three times in the Bible, always meaning simply "descendant" or "offspring" in a general sense (Genesis 21:23; Isaiah 14:22; Job 18:19).

The Septuagint translated the pair as "seed and name" (i.e., posterity), while Aramaic Targums rendered them as "sons and grandsons." By the tenth century CE, נֶכֶד began shifting toward the specific meaning "grandson": lexicographer Menahem Ben Saruq of Spain defined it as "grandsons" in his dictionary Ha-Machberet (mid-tenth century). Shortly after, Rabbi Chanokh ben Moshe of Córdoba used נִכְדֵי in a legal ruling to mean grandson. Medieval commentators generally agreed: נִין = son, נֶכֶד = son's son.

The word נִין entered the modern revival in two pocket dictionaries published between 1900 and 1903: Gur and Klausner's dictionary gave it as "descendant," while Ben-Yehuda and Steinberg's dictionary defined it as "grandson and great-grandson." As נֶכֶד settled into modern usage as "grandson," the question arose: what word covers the son of one's sibling?

Hebrew had traditionally used descriptive phrases: בֶּן אָח ("son of brother"), בֶּן אָחוֹת ("son of sister"). From 1902 onward, competing proposals circulated: S. Kokhav (1902) suggested repurposing נֶכֶד for nephew based on Luther's German translation (where it renders Neffe); Gur and Yellin's 1927 dictionary proposed נִין; Daniel Persky in Ha'aretz in 1932 proposed reviving אַחְיָן from 1 Chronicles 7:19, where it appears as a personal name. In 1939 someone coined דּוֹדָן as yet another candidate. The Va'ad HaLashon's Hebrew journal answered inquiries with "some propose נִין but the matter requires examination."

In 1943, the Va'ad HaLashon's grammar committee finally issued a definitive ruling: נֶכֶד = grandchild, שִׁלֵּשׁ = great-grandchild (biblical term revived), רִבֵּעַ = great-great-grandchild. נִין was declared to mean "descendant" (Nachkomme) in the broadest sense. The committee rejected אַחְיָן and proposed נֶכְדָּן for "nephew/niece," based on medieval evidence that נֶכֶד had sometimes meant "sibling's child." This ruling too failed to stick in practice. By the late 1940s and 1950s, newspapers used נִין inconsistently — sometimes for great-grandchild, sometimes for descendant, sometimes for nephew — and אַחְיָן gradually prevailed in everyday speech for nephew and niece.
