Here's a breakdown:
What are understood subject pronouns?
* They are implied: The pronoun is not directly written, but it's clear from the context who the subject is.
* They are usually "I" or "you": These are the most common understood subject pronouns because they often refer to the speaker or the listener.
Examples:
* "Can you please pass the salt?" (The understood subject pronoun is *you*.)
* "Going to the store later." (The understood subject pronoun is *I*.)
* "Enjoying the movie?" (The understood subject pronoun is *you*.)
* "Must have missed the bus." (The understood subject pronoun is *I*.)
Why are they used?
* Conciseness: Using understood pronouns makes sentences more concise and natural.
* Informal style: They are more common in informal speech and writing.
When to use them?
* When the subject is obvious: You can use an understood subject pronoun when the context makes it clear who is performing the action.
* When the subject is not important: If the focus is on the action or the object, the subject pronoun can be omitted.
Be careful with understood subject pronouns:
* Avoid ambiguity: Make sure the context makes it clear who the subject is.
* Consider formality: Avoid using them in formal writing.
