fairy แปลว่า

From Middle English faierie, fairie, from Old French faerie, from fae (from Latin fāta (“goddess of fate”)) + -erie. Equivalent to fay + -ry. Attested in English from about 1330, in King Alisaunder, first in the sense of "enchantment, illusion, dream" ("that thou herdest is fairye") and shortly thereafter "realm of the fays, fairy-land" and "the inhabitants of fairyland, collectively". The re-interpretation of the term as a countable noun denoting individual inhabitants of fairy-land can be traced to the 1390s, but became common only in the 16th century, perhaps due to reinterpreting phrases like faerie knight.
