من فرق modalو auxiliary رو درست متوحه شدم؟:
modal یه auxiliary هست اما برعکسش صحیح نیست.
این توضیحی که در زیر هست درسته؟
To be, to have, to do are primary auxiliaries. That is, they can function both as main verb (lexical verb) and as auxiliary.
- I have a car. (lexical use of 'to have', meaning 'to own')
- I have seen her. (auxiliary use of 'to have', to form the present perfect)
May, might, can, could, shall, will et cetera are modal auxiliaries. They cannot function as main verbs, which means they require a lexical verb to come after them.
- I will be the best chess player in the world.
