For example, if you use the adverb of frequency “always,” that action occurs 100% of the time. If you use the adverb of frequency “never,” that action occurs 0% of the time.

The present perfect continuous (also called present perfect progressive) is a verb tense used to discuss an action that started in the past and continues in the present moment. It’s used to talk about ongoing actions and recent actions that have an effect on the present.
The “singular they” is a third-person plural pronoun used in the singular form. It’s used when referring to a person whose gender is unknown or irrelevant or when referring to someone who uses “they” as a personal pronoun.
Historically, grammar sticklers have long argued that using “they” as singular was grammatically incorrect. However, many people use “they” as a singular pronoun in formal and informal writing and conversation.
Today, numerous style guides—including AP, APA, MLA, and Chicago—now accept and endorse the use of the singular they. Even dictionaries—including Merriam-Webster and Oxford—accept the use of the singular they as grammatically correct.
