I want to know the answer to the following question:
What term means "great vehicle"?
All the background I'm provided with is that "The Aṣṭasāhasrikā Prajñāpāramitā Sūtra, an early and important Mahayana text, contains a simple and brief definition for the term bodhisattva: "Because he has enlightenment as his aim, a bodhisattva-mahāsattva is so called."". Is that enough to answer the question?
Answer: yes
