It’s a phrase we use almost without thinking, isn't it? "I want to know." Whether it’s about the weather, a friend’s news, or a complex scientific discovery, that little urge to understand is fundamental to being human. But what exactly does "want to know" mean, and how do we use it correctly in English?
At its heart, "want to know" is pretty straightforward: it expresses a desire for information, a curiosity about something that is currently unknown. The words themselves are quite direct. "Want" signifies a desire or a need, while "know" means to possess information or understanding. So, "want to know" simply means to desire knowledge.
When we look at its pronunciation, it’s fairly consistent across different English accents. In British English, you’ll hear something like /wɒnt tu nəʊ/, and in American English, it leans towards /wɑːnt tu noʊ/. It’s a common enough phrase that most native speakers will understand it without a hitch.
But where things can get a little more nuanced is in how we construct sentences around it, especially when we're talking about asking questions within a question. This is where the concept of the "object clause" comes into play, and it’s something that often trips up learners.
Think about it this way: when you say "I want to know," you're essentially setting up a space for the information you're seeking. This space needs to be filled correctly. For instance, if you want to ask about someone’s name, you wouldn't say "I want to know what is his name." While it sounds like a direct question, within the structure of "I want to know," the word order needs to shift. It becomes "I want to know what his name is." The subject ("his name") comes before the verb ("is"). This is because the entire "what his name is" part is acting as the object of the verb "know." It’s no longer a direct question being asked, but rather the content of what you want to know.
Similarly, when we're talking about past events, the same rule applies. If someone "wanted to know" something that happened yesterday, the tense needs to align. So, "They wanted to know why she wanted to leave" is grammatically sound. The main verb "wanted" is in the past, and the information sought ("why she wanted to leave") also reflects that past context. Using "why does she want to leave" would be incorrect because the word order is wrong for an object clause, and the tense doesn't match the main verb.
Sometimes, instead of a direct question word like "what" or "why," we might use "if" or "whether" to introduce the information we're seeking, especially when there's a yes/no element. For example, "He wants to know whether he can attend the meeting or not." Here, "whether" clearly signals that the information sought is about a choice or possibility.
Interestingly, "want to know" isn't the only way to express this desire for information. You might also hear or see "would like to know," which is often considered a slightly more polite or formal way of saying the same thing. And if you're looking for a single word that captures that feeling of curiosity, "wonder" is a great synonym. "I wonder who is at the door" is very similar in meaning to "I want to know who is at the door."
So, the next time you find yourself saying "I want to know," take a moment to appreciate the simple yet powerful human drive behind it. It’s the engine of learning, the spark of conversation, and a fundamental part of how we navigate the world around us.
