Abstract
This study is focusing on anchogongs(按草工) in yeonggeonuigwes(營建儀軌), which were recorded with few details and in unsettled transcriptions. First, the positions and functions of anchogongs in $18^{th}$ censtury are analyzed by comparing to anchogongs in more detailed early $19^{th}$ century yeonggeonuigwes and those in extant buildings. Second, with the result, the historical significances are presumed in changing transcriptions of anchogong terms in those uigwes. In $18^{th}$ century uigwes, most of anchogongs are functioned as matbo-anchogongs and only four anchogongs in a gate building were used as jongryang-anchogongs. It is mainly because the sorts of buildings in $18^{th}$ century yeonggeonuigwes had only several varieties: most of the buildings belonging royal shrines. Transcriptions of anchogong terms had been changed for reflecting functional developments of anchogongs in $18^{th}$ century. However, reflections were much later than changes of actual functions.
