Chinese characters
The majority of simplified characters are drawn from conventional abbreviated forms, or ancient standard forms. For example, the orthodox character Lai  lai ("come") was written with the structure Lai  in the clerical script (Li Shu  / Li Shu , lishu) of the Han dynasty. This clerical form uses one fewer stroke, and was thus adopted as a simplified form. The character Yun  yun ("cloud") was written with the structure Yun  in the oracle bone script of the Shang dynasty, and had remained in use later as a phonetic loan in the meaning of "to say" while the Yu  radical was added to differentiate meanings. The simplified form adopts the original structure.
