The sign language videos uploaded on the YouTube channel SADeafSG by the Singapore Association for the Deaf (SADeaf) range from two seconds to six seconds long.
As of Tuesday, the playlist of 109 videos had had a total of 1,278 views.
Apart from signs for the different political parties, SADeaf included signs for words like "integrity", "corrupt" and "propaganda" along with other common political terms.
Some signs, such as for "freedom", "democracy/democratic" and "liberal", involve similar hand movements.
The sign for "vote" includes the action of marking the voting slip with an "X" and slipping it into the ballot box.
SgSL, the sign language used in the videos, has evolved organically over time from people in the deaf community here, SADeaf deputy director Alvan Yap said.
"The signs used in the videos have been long accepted by the local deaf community," he added.
