Infinitives Worksheets
About Our Infinitives Worksheets
Infinitives are the "to + base verb" words-like to jump, to read, to explore-that can act as nouns, describe nouns, or explain why we do something. These worksheets help students master that shape-shifting skill, making language more fluid and expressive. Instead of stumbling over "He wants to learn," students build that sentence with confidence.
Infinitives are everywhere-used for talking about goals ("I want to travel"), describing things ("a book to read"), or answering "why?" ("She ran to catch the bus"). These worksheets guide students from simple recognition to using infinitives with flair, and each PDF comes with an answer key to make learning self-checking and teacher-friendly.
A Look At Each Worksheet
Doggie Descriptions
Students write sentences describing dogs, using infinitives-like "A dog to protect the house." It's both visual and grammatical, combining cute prompts with structure, making the to + verb format seem simple and fun.
Gerund or Infinitive?
Learners decide whether each sentence needs a gerund (-ing form) or an infinitive ("to" + verb). It's a quick-thinking game that clarifies the difference-without rambling rules.
Infinite Infinitives
This worksheet dives deeper into variations of infinitives-exploring things like to have eaten (perfect infinitive) or to be chosen. It pushes students beyond basics into the rich possibilities of infinitive forms.
Infinitive Check
Students review sentences, spotting and correcting misuse of infinitives (like dropping "to" or using the wrong form). It sharpens editing skills and reinforces form clarity.
Infinitive Detectives
Text passages are hunted for infinitives-students circle or underline them. It's reading work that doubles as grammar awareness training.
Infinitive Identification
This sheet lists verbs or phrases with blanks-students name if they belong there as infinitives or not. It builds pattern recognition, step by structured step.
Infinitive Insights
Deeper explanation-focused worksheet that shows why we use infinitives in certain spots-like after particular verbs or to explain purpose. It ties rules to rationale, helping them stick.
Monster Phrases
Students break down long or complex infinitive phrases embedded in sentences ("to finish the project on time"). It's grammar with a dramatic twist-and students conquer the "monster."
Phrase Hunters
Scouring for infinitive phrases in passages, students pull them out and identify their role (subject, object, adjective, adverb). It transforms reading into phrase detective work.
Picture Phrases
Visual scenes prompt students to write sentences using infinitives-like "to climb the tall tree" under a drawn tree. Cute and contextual, this one makes grammar feel vivid.
Purposeful Infinitives
Here, students rewrite or complete sentences by adding an infinitive that expresses purpose ("He eats healthy to stay fit"). It connects form with function directly.
Sentence Fusion
Two separate sentences-one giving reason, one giving action-become one fused sentence using an infinitive. "She studied hard. She wanted to succeed." becomes "She studied hard to succeed." It teaches elegance in expression.
Split Fix
Students fix sentences where infinitives are incorrectly split-like "to boldly go" should be "to go boldly." It reinforces clean structure and clarity.
Triple Function
A single infinitive must be used as a noun, adjective, and adverb in different sentences-showing the three ways infinitives seamlessly transform their grammatical role.
Verb Connect
This worksheet links prompt verbs (like want, decide, ask) to the right infinitive phrases in blanks. It's junction practice for meaning and structure.
What Are Infinitives?
Infinitives are the "to + base form of a verb"-like to run, to learn, to imagine. They can act as nouns (To dream is free), adjectives (That's the book to read), or adverbs (He paused to listen). Flexible and functional!
Some verbs require infinitives afterward: plan to, hope to, decide to. Sometimes we drop "to"-the "bare infinitive," heard after let, make, help: Let me help (not "let me to help"). Knowing when to use the "to" version vs. the bare form is key.
Infinitives offer variety and precision in writing. They let students express purpose ("She moved to help"), intention ("I hope to learn"), or description ("a place to visit"). Mastering their roles helps transform simple sentences into rich, layered language.
Common Mistakes with Infinitives
Sentence - "I want go to the park."
Corrected Sentence - "I want to go to the park."
Why Is That Correct? - "Want" needs a full infinitive ("to go") after it-without "to," the sentence feels unfinished.
Sentence - "She made to wait."
Corrected Sentence - "She made me wait."
Why Is That Correct? - After "make" (causative verb), the bare infinitive (without "to") should follow-not "to wait."
Sentence - "He closed the door to quickly."
Corrected Sentence - "He closed the door too quickly."
Why Is That Correct? - "Too" indicates degree, not the infinitive marker. Mixing them up changes meaning-this correction restores clarity.
