In Grammar and Vocabulary 4.6, we learned the modal verb 識 sik1 (‘to know how to’). We learned that we can put a verb phrase for a skill or an activity after 識 sik1.

The word 識 sik1 can also be a verb. When 識 sik1 is a verb, it means ‘to know’. We put a noun (e.g., a language or a person) after it.
