Passive forms are a way to express the effect of a verb, rather than the cause or the verb itself. This series contains two primary topics: the Passive Voice, which involves the entire structure of a sentence; and Passive & Active Adjectives, which focuses on a noun phrase.
Most sentences are spoken or written in ‘Active’ voice; they focus on a subject noun that does the action or has a state. Sometimes it’s better for the focus of a sentence to be a passive noun. Using an altered sentence structure, we can express the result of an action. Here, the focus of the sentence is not on the noun doing the action, but on a noun affected by the action (a noun that would otherwise be an object of an active sentence).
Passive & Active Adjectives are also known as Participle Adjectives. Adjectives that end with ‘-ed’ show how the modified noun is affected by an action or state. Adjectives that end with ‘-ing’ show how the modified noun causes an action or state. Without those suffixes, the words are verbs. In fact, it’s helpful to consider both of the adjectives and their related verb together in terms of how they affect or are caused by the noun those adjectives modify.
