What it means
تکفرزند (tak-farzand) means only child, a person who grows up without brothers or sisters. The compound joins تک (tak, single), which Wiktionary traces to either Turkic tek or Middle Persian tag depending on the sense, with فرزند (farzand), a word inherited directly from Middle Persian frazand meaning child or offspring. Because the two parts carry different historical roots, linguists treat the compound as mixed in origin. The phrase is neutral in register and appears in both spoken conversation and formal writing. A near-synonym in more formal contexts is فرزند یگانه (farzand-e yegane), though تکفرزند is the term you will hear in daily speech.
How to use it

Cultural note
Iran’s total fertility rate has fallen sharply since the 1980s, and single-child families are now common in urban areas, particularly Tehran. This shift has made تکفرزند a live topic in public debate, with government campaigns at various points encouraging larger families and researchers studying how only children fare in an extended-family culture that traditionally prizes sibling bonds. Grandparents and older relatives sometimes express concern that a تکفرزند will lack companionship or become overly dependent on parents, while younger urban couples often point to economic pressures as the deciding factor.
