Gerunds & Infinitives

What are Gerunds & Infinitives?

Two non-finite verb forms that allow a verb to function as a noun, adjective, or adverb — each following different patterns with different verbs, prepositions, and structures.

A gerund is a verb ending in -ing that functions as a noun: Swimming is good exercise. I enjoy reading. It names an activity or process as if it were a thing.

An infinitive is the base form of a verb preceded by to: To learn is a privilege. She wants to leave. It expresses purpose, intention, or a potential action.

Both can follow certain verbs — but many verbs require specifically one or the other, and some take both with a difference in meaning.

Gerunds vs Infinitives — At a Glance

Gerunds & Infinitives in Daily Life

Situation 1 — Talking About Hobbies

Describing what you enjoy, love, or can't stand — this is the natural home for gerunds. The gerund treats the activity as a thing you engage with.

"I took up running about three years ago and now genuinely can't imagine not doing it. I also enjoy cooking, though I avoid baking because I lack the patience."

Situation 2 — Making Plans

Future plans and intentions use infinitives — because they describe what is not yet real.

"I'm planning to apply for a transfer. I've decided to wait until the end of the quarter. I hope to hear back within two weeks."

Situation 3 — Asking Permission and Making Offers

Both structures appear constantly in polite professional and social language.

"Would you mind helping me with this?" (gerund after "mind") "I'd be happy to assist with the report." (infinitive after adjective)

Situation 4 — Explaining Why (Purpose)

Infinitives of purpose explain the reason behind an action.

"She left early to avoid getting stuck in traffic. He called ahead to check availability. They hired an extra assistant to handle the overflow."

Situation 5 — Talking About Memories and Habits

Here the gerund/infinitive choice changes meaning completely.

"I remember locking the door." (I locked it — I have a memory of doing it) "I remembered to lock the door." (I didn't forget — I did it because I remembered I should)

Sentences — Beginner to Advanced

Beginner

"Swimming every morning is something I started three years ago and now genuinely can't imagine stopping."

"Swimming" = gerund as subject. "Stopping" = gerund after "imagine". Both natural and automatic.

Beginner

"She left early to avoid getting stuck in traffic, which meant missing the end of the meeting."

"To avoid" = infinitive of purpose. "Getting" = gerund after avoid (avoid always takes a gerund). "Missing" = gerund after "meant".

Intermediate

"He tried calling the office three times but nobody picked up, so he decided to go in person."

"Tried calling" = tested one method to see if it worked (the calling happened). "Decided to go" = formed an intention (going is future/intended).

Intermediate

"Having spent two years studying the subject, she felt confident enough to present her findings to the board."

"Having spent" = perfect participle — the studying is complete before the presentation. "To present" = infinitive showing intention/purpose.

Advanced

"I regret not having called earlier — not as an excuse, but as an acknowledgment that the timing made everything that followed harder than it needed to be."

"Regret not having called" = perfect gerund after "regret" — the not-calling preceded the consequences. More precise than "regret not calling".

Advanced

"To have mastered a second language is to have gained access to a second consciousness — a different way of organizing reality."

"To have mastered" and "to have gained" = perfect infinitives as subjects. Elevated, philosophical register — natural in formal essays.

How Gerunds & Infinitives Elevate a Sentence

Choosing between gerund and infinitive — and deploying both with precision — transforms flat sentences into nuanced, authoritative ones.

Basic: "I didn't check the figures. Then I sent the report."

Elevated: "I sent the report without having checked the figures — a mistake I now try hard to avoid repeating."

"Without having checked" (perfect gerund after a preposition) shows that the missing check came before the sending. "Try to avoid" adds an infinitive of effort followed by avoid + gerund. Two non-finite forms turn two flat sentences into one precise one.

Memory Tips

Gerund = Looking Back

Gerunds tend to follow verbs that look backwards at real, completed, or ongoing experiences: enjoy, admit, regret, avoid, finish, practice, consider. The activity is real and existing.

If the action is real, happening, or in the past — lean towards the gerund.

Infinitive = Looking Forward

Infinitives tend to follow verbs that look forwards at intentions and not-yet-real actions: want, hope, plan, decide, promise, manage, fail, expect. The action is intended or attempted.

If the action is intended, potential, or not yet done — lean towards the infinitive.

After prepositions — always gerund

"interested in going", "good at explaining", "before leaving", "by working harder", "after finishing"

The rule is reliable: when a verb follows a preposition, use the gerund, never the infinitive.

Formal vs Informal

Informal:

"I can't stand waiting. Are you thinking of coming tonight? I'm hoping to leave early."

Gerunds and infinitives appear naturally and instinctively — no conscious decision needed at this level.

Formal:

"To ensure compliance with the revised guidelines, all departments are required to submit updated procedures by the end of the month."

"To ensure" = infinitive of purpose (formal). "To submit" = infinitive after "required" (formal obligation structure).

Academic / Elevated:

"Having reviewed the available evidence, the committee concluded that the proposed measures were unlikely to achieve the stated objectives."

"Having reviewed" = perfect participle clause (common in academic and legal writing). Signals the reviewing is complete before the conclusion.

Idioms with Gerunds & Infinitives

Many powerful idioms work as gerunds — treating an idiomatic action as a noun-like concept.

"to think outside the box" (infinitive)

Meaning: To approach a problem creatively and unconventionally.

"The brief was simple: to think outside the box and come up with an approach that competing firms hadn't considered, rather than simply refining what already existed."

"To think outside the box" = infinitive explaining what the brief was. "Refining" = gerund after rather than. Note that "competing" here is a participle used as an adjective (competing firms), not a gerund.

"burning bridges" (gerund)

Meaning: Permanently destroying a relationship or opportunity.

"She warned that accepting the offer would mean burning bridges with her current employer — and that rebuilding that kind of professional trust, once lost, was rarely possible."

Three gerunds in sequence: accepting, burning, rebuilding — all natural, all precise. "Burning bridges" is the idiom; the gerund form integrates it perfectly into the sentence.
