Meaning
Hello, grammar builders. Today, we are going to learn about a great team. We are going to learn about a verb and an infinitive. A verb is an action word. It tells us what someone or something does. Words like run, eat, sleep, and play are verbs.
An infinitive is a special form of a verb. It is the basic, name-of-the-action form. It almost always has the word "to" in front of it. "To run," "to eat," "to sleep," "to play." That is the infinitive. It shows the idea of the action, not the action happening right now. When a verb and an infinitive work together, the first verb sets up the action, and the infinitive tells us what that action is. "I want to play." The verb "want" sets up the feeling. The infinitive "to play" tells us what I want to do. Let's see how this great team works.
Conjugation
The infinitive does not change. It does not conjugate. The word "conjugate" means to change for different people or times. The infinitive stays the same. It is always "to" plus the base verb.
Look at the main verb. That is the one that can change. I want to play. You want to play. He wants to play. She wants to play. The dog wants to play. We want to play. They want to play. See. The main verb "want" changes for he/she/it (wants), but the infinitive "to play" stays exactly the same. It is a steady partner. This makes it easy to spot once you know to look for "to" plus a verb.
Present tense
We use a verb and an infinitive together a lot in the present tense. We use it to talk about things we like, need, want, or plan to do now.
I like to draw. You need to listen. He wants to eat pizza. She hopes to win. We plan to go to the park. They love to swim. In these sentences, the first verb (like, need, want, hope, plan, love) is in the present. The infinitive tells us the specific action connected to that feeling or plan.
We also use it after the verb "to be" to talk about a purpose or a job. My job is to clean my room. Her dream is to be a pilot. The goal is to have fun. Here, the infinitive explains what the job, dream, or goal actually is.
Past tense
The infinitive itself does not have a past form. It is always the basic "to + verb." But we can use it with verbs that are in the past tense. This talks about past desires, plans, or needs.
I wanted to call you yesterday. The verb "wanted" is in the past. The action I desired, "to call," is in the infinitive. She needed to finish her work. He hoped to see you. We planned to visit the museum. They decided to leave early.
Even though the main feeling (wanted, needed, hoped) happened in the past, the action that was wanted is still expressed with the unchanging infinitive. This is a very common and useful pattern.
Future tense
A verb and an infinitive are also important for the future, especially with "going to."
I am going to read this book. You are going to love this game. She is going to be a scientist. They are going to build a fort. Here, "am going," "are going," "is going" show a future plan. The infinitive ("to read," "to love," "to be," "to build") tells us what that future action will be.
We also use it after the verb "will." I will try to help. You will learn to ride a bike. He will remember to bring it. We will forget to call. The infinitive comes after "will" to complete the idea of the future action.
Questions
We can ask questions that use a verb and an infinitive. These questions often start with "what," "where," or "how," and they ask about plans, desires, or abilities.
What do you want to do? Where do you like to go? How did you learn to swim? When are you going to start? Do you need to leave now? Can you help me to carry this?
In these questions, the infinitive comes at the end, completing the thought. It tells us the specific action related to the question word. Learning to use infinitives in questions helps children express their plans and ask about others' ideas clearly.
Other uses
We use a verb and an infinitive to show purpose, or the reason why we do something. I went to the store to buy milk. "To buy" tells us the purpose of going. She is saving money to buy a new bike. He stood up to see better.
We use the infinitive after many adjectives. I am happy to see you. It is easy to learn. He was surprised to find the key. The infinitive explains the reason for the feeling.
We also use it in short suggestions, often with "let's." Let's go to play. Let's try to be quiet. Here, the infinitive gives the goal of the suggestion. The team of a verb and an infinitive helps us express so many different ideas.
Learning tips
A great way to spot infinitives is to look for the word "to" followed by an action word. Play a "To Hunt" game. Read a simple story. See how many times you can find "to" followed by a verb like "to run," "to eat," "to sleep." Circle them. This trains your eye to see the pattern.
Think of the infinitive as the "name" of the action. The verb "jump" has the name "to jump." The verb "sing" has the name "to sing." This simple idea helps separate the infinitive form from its conjugated versions (jumps, jumped, jumping).
Use a "Verb Chain" game. Start with a sentence like "I like..." The next person must add an infinitive. "I like to dance." The next person says, "I like to dance and to sing." Keep adding new infinitives to the chain. This is fun and reinforces the structure.
Educational games
Let's play "Infinitive Charades." Write down many infinitives on small papers: to swim, to eat, to laugh, to fly, to read. Players take turns picking a paper and acting out the action without speaking. The other players must guess. They must say the full infinitive phrase, "to swim!" not just "swim!" This connects the physical action directly to the grammatical form.
Try the "Sentence Builder" game. Prepare two sets of cards. Set A has sentence starters with verbs: "I want...", "She likes...", "We need...", "He is going...". Set B has infinitive cards: "...to play.", "...to read.", "...to eat.", "...to run." Players pick one card from each set and read the silly or sensible sentence they create. "I want to eat." "She likes to run." This visually and verbally practices the common starter verb + infinitive structure.
Create an "Infinitive Purpose" scavenger hunt. Give kids a simple list of purposes using infinitives. "Find something you use to write (a pencil). Find something you need to drink (a cup). Find a place you go to sleep (your bed). Find something you wear to stay warm (a coat)." They run around finding objects or places that match the purpose phrase. This game links the grammar concept of a verb and an infinitive directly to their real-world understanding of function and reason, making the lesson tangible and memorable.
