하낱도

Univerbation of 한 (han, “one”) +‎ 낱 (nat, “piece”) +‎ 도 (-do, “even”).

하낱도 • (hanatdo)

1. (Gyeongsang, with a negated sentence) even a little

   하낱도 안 부꾸럽다. (Gyeongsang dialect, Changwon)

   Hanatdo an bukkureopda.

   It's not even a little shameful.

• Speakers of other dialects often think this is a dialectal form of 하나도 (hana-do, “even one; even a little”), but 하나도 (hana-do) and 하낱도 (hanatdo) are both used in Gyeongsang and the two have separate etymologies.
