sinpin

sinpin refers to objects that face directions. walls can easily be sinpin, and so can human faces or any of the front part of an animal. the part of a building that faces the road can be sinpin. So can any other walls of the same building, though. By using sinpin to describe a surface, you're drawing attention to the directionality of it. When one rolls a die, perhaps the most crucial sinpin is the one facing up. At an art museum, even if a painting were to be placed on the ground face up, sinpin is still the best word to describe its physicality because the concept of using it as one would use a supa is disrespectful to the artist and the artwork. While sinpin is usually used for vertical surfaces, it is these examples of usage that restrict me from describing it as strictly such. sinpin is in contrast with supa.

sinpin also refers to the space that something else faces. "sinpin tomo" can mean both "front surface of the house" and "the place in front of the house."

sinpin can't be extended into a metaphorical space to talk about time. "tenpo sinpin" might mean future or past to people from different cultures, so in order to use it like that you'd need to build it up by explaining the metaphor. For example, if you framed yourself as facing the past and walking backwards, you could even use "tenpo sinpin" to talk about the past!
