# 으로써 (-ulosse)
*Allomorph*: 로써(-losse)
## [ss Instrument] and [ss Means]
Equivalent to [으로 (-ulo)](http://flat.nert.georgetown.edu/ko/으로/)'s [ss Instrument], 으로써 marks [ss Instrument] when the nominal is an object:
[gex 001 "{망치로써[p ko/로써 Instrument]||hammer-with} {컵을 cup-ACC} {깨트렸다 broke}." "(I) broke the cup with a hammer."]
When marking an action that causally mediates the main event, 으로써 is annotated as [ss Means].

We annotate "material" sense of 으로써 as [ss Source--Instrument]:
[gex 003 "{쌀[p ko/로써 Source--Instrument]||rice-with} {떡[p ko/을 Theme]||rice cake-ACC} {만든다 make}." "(One) makes rice cakes with rice."]
## [ss Time]
