Nara, what?

JLPT1 G7 S8 F841

A variant of 柰 as described in 款 (carve characters), here suggesting that the production of the characters involves not carving but rather pressing an implement downward into soft clay (compare the derivative character 捺). *How* and *what* are borrowed meanings. 奈 is also used in transliterations, such as 奈落 (Sanskrit or Pali: naraka), referring to hell/purgatory or the underworld in general.
