Navigating workplace English requires more than just knowing vocabulary; you need to master the grammar behind polite requests, apologies, and standard email phrases. The key to sounding natural lies in knowing when to use gerunds (-ing forms) and infinitives (to + verb).

Gerunds After Prepositions

Any time a verb directly follows a preposition (such as for, in, about, or with), it must take the gerund (-ing) form. This rule is crucial for workplace apologies and explanations.

✅ I sincerely apologize for missing the meeting today. ❌ I sincerely apologize for miss the meeting today.

One of the biggest edge cases that trips up learners is the phrase look forward to. Because we are used to seeing to as part of an infinitive (like to go or to write), it feels natural to use a base verb. However, in the phrase look forward to, the word to is a preposition. Therefore, it must be followed by a noun or a gerund.

✅ I look forward to hearing from you soon. ❌ I look forward to hear from you soon.

Gerunds After Specific Verbs

Certain verbs dictate that the action following them must be a gerund. In business communication, the verb mind is frequently used to make polite requests, and it always takes an -ing verb.

✅ Would you mind muting your microphone? ❌ Would you mind to mute your microphone?

Infinitives of Purpose

When you need to explain your reason for doing something—such as why you are sending an email or calling a meeting—use the infinitive form (to + base verb). This is called the infinitive of purpose.

✅ I am writing to update you on the project status. ❌ I am writing for updating you on the project status.

Essential Professional Collocations

Grammar isn't just about rules; it is also about collocations (words that naturally go together). Virtual meetings and emails have their own set of fixed phrases that you simply need to memorize:

• Attachments: Use "Please find attached the report" rather than "Please look attached."
• Virtual Meetings: When someone's audio is off, they are "on mute," not "in mute."
• Following Up: When checking on a previous message, you are "following up" on it.

A Common Learner Error

A frequent mistake is mixing up the grammar when interrupting or apologizing. You can use either sorry to + base verb OR sorry for + gerund. Learners often blend the two by mistake.

✅ Sorry to interrupt, but could you explain that again? ✅ Sorry for interrupting, but could you explain that again? ❌ Sorry for interrupt, but could you explain that again?

Choosing one structure and sticking to its rule will instantly make your professional English sound more polished.
