lyse Subject-Verb Agreement

📝

Notes from a Native English Speaker

Subject-verb agreement means that a subject and its verb match. They’re either both plural or both singular. A singular subject takes a singular verb. - Example: The cat is sleeping. A plural subject takes a plural verb. - Example: The cats are sleeping.

In the present tense, 'lyse' follows the typical rule of adding 's' when the subject is third person singular (he, she, it), but it remains the same for all other subjects (first person, second person, and plural subjects).
