Verbs followed by the nominalizer རྒྱུ་ correspond to the future or the imperfective, often with a sense of obligation. The functions of the nominalizer རྒྱུ་ are analogous to those of ཡག་, though it has more formal, and rather literary, overtones.

• དེབ་ཁྱེར་རྒྱུ་བརྗེད་བཞག “I’ve forgotten to bring the book.”
• དགོན་པ་ཆུང་ཆུང་མང་པོ་མཇལ་རྒྱུ་འདུག “There are many small monasteries to visit.”
