Backward

Dwiro (뒤로) is the Korean word for “backward” or “toward the back”. Kumdo texts use it for moving or stepping back, for example after a strike in toegyeok (퇴격) or when retreating with mireogeotgi (밀어걷기).

Dwiro (뒤로) is a Korean word meaning “backward” or “toward the back”.

I found no definition of dwiro as a technical term of kumdo in its own right. In the texts it is an ordinary word that gives the direction of a movement. Examples found:

The Korea Kumdo Association (대한검도회) manual describes a strike to the head (meori, 머리) from the kodeungissaum (코등이싸움) position. After striking, the attacker withdraws backward (dwiro ppajinda, 뒤로 빠진다).
Toegyeok (퇴격) is a strike made while stepping back during the mombadeum (몸받음) or the kodeungissaum. A Korean source says that after the strike one moves backward with mireogeotgi (밀어걷기), takes jansim (잔심) and returns to jungdanse (중단세).
The same source says one must not step back during the mombadeum.
Another text warns that someone who gives way to the opponent's pressure and pulls back (dwiro ppaeda, 뒤로 빼다) cannot expect the technique to succeed.
The Incheon federation's guide to the bon (본) gives the entering and leaving steps as three steps forward, vigorously, and five steps backward (dwiro), carefully.
