missing 'to' after 'look forward'

Many learners drop the preposition to after look forward and write sentences like "I look forward meeting you." That's incorrect: look forward must be followed by to + a noun or to + a gerund (verb+ing). Below are clear rules, quick repairs you can paste into emails, plenty of wrong/right pairs for work, school and casual use, and a memory trick to stop the mistake.

Quick answer: Do you need "to" after look forward?

Yes. Use look forward to + noun or look forward to + gerund (verb+ing). The to here is a preposition, not the infinitive marker.

Correct: I look forward to meeting you. (gerund)
Correct: I look forward to your reply. (noun)
Wrong: I look forward meeting you. → Fix: I look forward to meeting you.

Core grammar: the exact pattern

Treat look forward + to as a set: look forward (verb) + to (preposition) + object. After prepositions use nouns, pronouns, or gerunds (verb+ing).

Pattern: look forward to + noun / pronoun / gerund.
If you need an infinitive meaning, use a different verb: I hope to meet you; I plan to meet you.

Wrong: I look forward meeting you.
Right: I look forward to meeting you.
Wrong: I look forward to speak with the manager.
Right: I look forward to speaking with the manager.

Real usage and tone: choose the right register

Both I look forward to and I'm looking forward to are correct. Use I look forward to for a formal business tone and I'm looking forward to for a warmer or more conversational tone. Short forms like Looking forward to it! work in casual messages but not in formal letters.

Formal: I look forward to your response.
Neutral/professional: I'm looking forward to our call next week.
Casual/text: Looking forward to it!

Fix your sentence: quick repairs and reusable rewrites

Memory trick and quick tests

Mnemonic: Treat to as toward. You look forward toward something - toward + action → use -ing (toward doing).

Two quick checks you can run in 10 seconds:

Replace what follows to with a clear noun (your reply). If it still makes sense, you're good.
If the object is an action, convert the verb to -ing. If you see a bare verb after to, it's probably wrong.

Quick test: I look forward to (your reply) - OK. I look forward to (meet you) - change to meeting.

Hyphenation, spacing and punctuation (short notes)

Do not hyphenate the phrase. Use normal spacing and punctuation. Starting a sentence with Looking forward to... is fine in casual messages but avoid it in formal letters.

Not hyphenated: I look forward to the workshop.
Spacing: one space after commas and periods as usual.
Punctuation: I look forward to hearing from you. (period as normal)

Similar mistakes to watch for

The same error pattern appears with other preposition + gerund phrases. Also check meaning: wait for, look forward to, and hope to are not interchangeable.

fond of / good at / tired of → use gerund: I am fond of swimming (not I am fond of swim).
Don't replace look forward to with wait for unless the nuance fits: wait for is neutral; look forward to implies positive anticipation.
If you see to + base verb, confirm whether that to is an infinitive (I want to meet) or a preposition (look forward to meeting).

Wrong: I'm fond of to swim. →
Right: I'm fond of swimming.
Wrong: I wait for meeting you. →
Right: I look forward to meeting you. / I can't wait to meet you.

FAQ

Can I say "I look forward meeting you"?

No. The correct form is I look forward to meeting you. The preposition to must be followed by a noun or a gerund (meeting).

Is the "to" in look forward to the same as the infinitive to?

No. In this phrase to is a preposition. After prepositions use nouns, pronouns, or gerunds (verb+ing), not a bare infinitive.

Should I use "I'm looking forward to" or "I look forward to" in a business email?

Both are correct. I look forward to is slightly more formal; I'm looking forward to is warmer and fine in many professional emails.

Can I follow "look forward to" with a clause (that...)?

Yes. You can write I look forward to the fact that you will attend, but it's more natural to use a noun or gerund: I look forward to your attending / I look forward to you attending.

How do I change a sentence if I used a base verb after "to"?

Change the verb to -ing (meet → meeting) or rewrite with a verb that takes an infinitive (e.g., I hope to meet you).
