کاب kâb
*Fr.: cube *
*Geometry*: The regular solid whose faces are six squares.
*Algebra*: The third power of a quantity; the product of three equal factors
(*a . a . a = a*^{3}).
From L. *cubus*, from Gk. *kubos* "a cube, a die; cavity before the hip,"
*kubiton* "elbow;" cf. Skt. *kubra-* "hole in the earth, pit;" Goth. *hups* "hip;"
from PIE base **keu-* "to bend." The currently used term in Pers. is *moka'ab* (مکعب), loan from Ar.,
from *ka'b* (کعب)
"talus, anklebone, heel; die." There are several Pers. equivalents for the concepts
"talus, anklebone; die," one of which *qâb*, variants *qâp* and
in Tabari *kâb* "heel, talus." This dictionary adopts *kâb*, which has already
been introduced by other sources. |
