When you want to talk about what someone else should do in English, you use the pattern "want someone to be" followed by an adjective or noun. The "to" is essential here, not optional.
The sentence "They want you to be happy" works because "to be" is an infinitive phrase that comes after the verb "want." Many learners drop the "to" by mistake, writing "they want you be happy," which is grammatically incorrect. Understanding this structure opens up a whole category of English verbs that work the same way.
The Infinitive Rule: Want + Object + To + Verb
When you use "want" with another person as the object, you always need "to" before the next verb. This is different from when you want something for yourself. You say "I want to be happy" (infinitive), but "They want you to be happy" (object infinitive). The presence of another person between the verb and the infinitive requires the "to."
Other verbs follow this exact pattern: "I need you to help me," "She asked him to wait," "We expect them to arrive on time." Once you recognize the structure, you can apply it to dozens of verbs in English.
Real Sentences You Will Actually Use
Instead of memorizing rules in isolation, here are sentences you might say or hear in real conversations. "My parents want me to study medicine." "The teacher asked us to submit our homework on Friday." "Do you expect him to call today?" "I need her to understand this is serious." Each one follows the same rule: object + "to" + verb.
The mistake happens because some languages do not require this structure, or because learners confuse it with simpler infinitives. When you hear native speakers, you will notice this pattern everywhere, especially in everyday speech. Paying attention to real conversation is how the rule becomes automatic instead of something you have to think about.
Why Speaking Practice Makes Grammar Stick
Reading a grammar explanation once is not enough to make this second nature. You need to produce the sentences yourself, out loud, in real conversation with someone who speaks English natively. When you stumble and say "They want you be happy" and a native speaker corrects you gently in the moment, your brain holds onto it.
PBC Languages runs free language exchanges where you are paired with a native English speaker. These exchanges are not structured lessons, they are genuine conversations. You both take turns speaking in each other's target language. When you are actually talking, not just reading, mistakes like missing the "to" come up naturally, and you learn from the correction immediately.
Small group classes at PBC Languages work the same way. With a maximum of four students per class, you get real speaking time. In a large classroom you can hide and listen, but in a group of four you have to talk. The teacher will notice when you leave out the "to" and help you in that moment. Consistency matters more than intensity, so showing up regularly to practice with real people is what builds fluency.
Free Resources to Get You Started
You do not need to wait for a class to start getting comfortable with this structure. Begin noticing it when you watch English content, read subtitles, or listen to podcasts. Every time you hear "want someone to," stop and notice it. Your brain is learning even when you are just absorbing language naturally.
When you are ready to practice speaking with a native English speaker, PBC Languages offers free language exchanges. You pair up with someone learning your language, and the exchange is genuinely free, always. No app, no subscription, no payment. Two people simply connecting and helping each other learn.
If you want structured guidance alongside your speaking practice, the first class at PBC Languages is free as well. Teachers are chosen individually to match your level and your learning style. Between classes, WhatsApp groups keep the learning alive and community strong. Sign up at pbclanguages.com to book your free exchange or free class.
