When do you use an understood you?

You're asking about the grammatical term "understood you," which refers to a situation where the pronoun "you" is omitted because it's implied by the context. It's not technically a separate grammatical term, but rather a description of how we often use language in a more concise way.

Here are some examples:

* "Call me tomorrow." This sentence implies "Call *you* me tomorrow," but the "you" is understood because the speaker is addressing the listener directly.

* "See you later." This implies "See *you* later," with the "you" understood because the speaker is addressing the person they are speaking to.

* "Thank you for your time." This implies "Thank *you* for your time," with the "you" understood because the speaker is addressing the person they are thanking.

Essentially, you use an "understood you" whenever the context makes it clear who the pronoun "you" refers to, even if it's not explicitly stated.

Here's a breakdown of how this works:

* Direct address: When speaking directly to someone, the "you" is often understood because the speaker is addressing them personally.

* Implied subject: Sometimes, the "you" is implied by the verb or the overall context of the sentence. For example, "I'll be there soon" implies "I'll be there soon *for you*."

While grammatically correct, using the "understood you" can sometimes feel less formal or less polite. However, it's a common and natural part of everyday language.
