Glad to Hear vs. Glad to Know – Which is Correct?
Both phrases “glad to hear” and “glad to know” are correct English expressions. Use “glad to hear” when responding to information you have received, especially news or an update. Use “glad to know” when emphasizing awareness, certainty, or reassurance. Their meanings overlap, but context determines the most natural choice.
Because “hear” and “here” are often confused, reviewing “Hear” vs. “Here” can sharpen this distinction.
Glad to Hear or Glad to Know – Which is Correct?
Both “glad to hear” and “glad to know” are correct. They express happiness or relief about information, but they emphasize different aspects of that information.
“Glad to hear” is usually used as a response to something someone has said or reported. It often introduces a reaction to news, an update, an opinion, or a personal statement.
“Glad to know” focuses more on having knowledge, certainty, or reassurance. It is especially natural when the information helps you understand a situation or feel confident about something.
The Best Trick to Remember the Difference
Use the communication test: if someone has just told you something, choose “glad to hear.” If the important point is that you now possess useful knowledge or reassurance, choose “glad to know.”
For example, “I’m glad to hear you arrived safely” reacts to the person’s update. “I’m glad to know you’re safe” emphasizes the reassuring fact itself. In many situations, either phrase is grammatically correct, but one may sound more natural depending on the focus.
| Word | Part of Speech | Meaning | Example |
|---|---|---|---|
| glad to hear | Adjective phrase | Pleased by information someone has communicated | I’m glad to hear that your presentation went well. |
| glad to know | Adjective phrase | Pleased or reassured by having knowledge of something | I’m glad to know that the documents were received. |
How to Use Glad to Hear
“Glad to hear” is used when you are pleased by something you have just heard, read, or received as an update. Although it literally refers to hearing, modern English often uses it for information received through email, text messages, reports, or other forms of communication.
This expression is common in friendly, professional, and customer-service communication. It sounds warm and natural without being excessively informal. The expanded form, “I’m glad to hear that…”, is often used in complete sentences, while the shorter form, “Glad to hear it,” is common in conversation.
Example 1: I’m glad to hear that you are feeling better.
Example 2: We’re glad to hear that the client approved the proposal.
Example 3: “I passed my exam.” “Glad to hear it!”
Etymology of the Phrase Glad to Hear
Glad comes from Old English glæd, meaning bright, joyful, or pleased. Hear comes from the Old English verb hīeran, meaning to perceive sound or receive information. The phrase developed from the broader idea that receiving news is a form of hearing, even when the information arrives in writing or electronically.
How to Use Glad to Know
“Glad to know” is used when you are pleased, relieved, or reassured by awareness of a fact. It often highlights the value of knowing something rather than the act of receiving someone’s message.
The phrase is useful when discussing safety, plans, expectations, rules, decisions, or other facts that provide certainty. It can also sound slightly more deliberate than “glad to hear,” especially in professional or reassuring statements.
Example 1: I’m glad to know that someone will be available to help.
Example 2: She was glad to know that her application had been received.
Example 3: It’s glad to know that the company takes customer privacy seriously.
In the third example, the natural wording is actually “It’s good to know” or “I’m glad to know.” The phrase normally requires a subject such as I’m, we’re, or she’s before glad.
Etymology of the Phrase Glad to Know
Glad originated from an Old English word associated with brightness, happiness, and pleasure. Know comes from the Old English verb cnāwan, meaning to recognize, understand, or have knowledge of something. Together, the words express pleasure or relief resulting from awareness.
