I get confused when I speak vs. write in English—are these sentences both correct?

Asked bySam SentencePosted Mar 24, 2026 5:35 PM3 answers27 upvotesCanonical URL

Hi everyone! I’m preparing for a work presentation and also writing an email to my boss in English. I noticed I say things differently out loud than when I write. For example, when I speak, I say, “I’m gonna finish the report tomorrow,” but when I write, I use, “I will finish the report tomorrow.”

Is it normal to use more informal sentences when speaking? Should I avoid things like “gonna” and contractions like “I’m” when I write emails? How do native speakers decide what’s okay for spoken English versus written English? I’d appreciate some advice or examples!

Context:
Preparing for a business setting, aiming for professional American English.

Explanation:
It's very common to use different patterns when speaking versus writing. Spoken English usually allows more informal structures, while written professional English is typically more formal.

Pattern:

  • Spoken: Informal contractions/slang (e.g., "gonna," "wanna," "I'm"), direct tone.
  • Written: Formal vocabulary and structure (e.g., "will," "am going to"), limited contractions, polite phrasing.

Examples:

  • Speaking: "I'm gonna send the file later."
  • Writing: "I will send the file later."
  • Speaking: "Can you give me a sec?"
  • Writing: "Could you please give me a moment?"

Practice suggestion:
Before you click 'send' on a business email, review your sentences and replace spoken shortcuts (like "gonna" or "wanna") with their formal equivalents (like "going to" or "want to").

Self-check:
When editing, ask: "Would I use this sentence in a formal letter to someone I don't know well?"

Explanation:
Spoken and written English often differ in formality and word choice. Recognizing which features are typical in each helps you adjust your style for the context.

Examples:

  • Spoken: "I'll get back to you soon."

  • Written (email to boss): "I will respond to you soon."

  • Spoken: "Let's figure it out."

  • Written: "Let us discuss solutions."

Notice that in writing, especially in business emails, contractions like "I'll" or "let's" and conversational phrases are usually replaced with more formal structures.

Practice:
Take a short sentence you might say aloud at work. Write it as you'd speak, then rewrite it for an email to your boss. Compare - what changed?

Explanation:
Native speakers often use an internal checklist when deciding between spoken and written English in professional settings. Here’s a checklist you can use:

  1. Look for informal words (like "gonna", "kinda", "wanna") – replace them with formal alternatives.
  2. Limit contractions (like "I'm", "you're") in formal emails, though some contractions ("I'm") are acceptable depending on the company's culture.
  3. Aim for clear, direct language without slang or filler words.

Examples:

  • Incorrect for formal writing: "I'm gonna talk to the client."

  • Correct for formal writing: "I am going to speak with the client."

  • Incorrect for formal writing: "I'll get it done ASAP."

  • Correct for formal writing: "I will complete it as soon as possible."

Practice Tip:
Before sending an important message, read it aloud and check off each point on your checklist. If you spot any informal words, swap them for their formal equivalents.
