Few ways to incorporate new words:
- Using the ལོག་ཡིག (flipped letters): ཁེ་ཎ་ཌ། (Canada)
- རྗེས་གྲུབ། Name based on what the meaning is: གློག་ཀླད། (computer, lit. electric brain).
- འདོད་རྒྱལ། Arbitrarily like ཆུ། (water).
- Understand the two parts and render those into Tibetan སེམས་མཁམས་རིག་པ་བ། (སེམས་མཁམས། psychic རིག་པ། logic).
Initiatives like Emory-Tibet Science Initiative (ETSI) are constantly thinking about those.
This reminds me of the document I found in Amithaba Monastery with many medical terms: Tibetan Psychology Vocabulary.
