លោក(louk, “sir”) +អ្នក(neak, “a polite term of address in Khmer society for someone without calling their name directly”) +ឧកញ៉ា(ʔokɲaa, “the second highest royal title”). This is a title for a classical Khmer official which was coined in the eighteenth century, replacing the much older សម្ដេចចៅពញា(sɑmdach chav pɲie), an ancient high military rank.
