Why Is It Useful to Underline on WhatsApp?

Although not natively available, underlining can be a very useful formatting option on WhatsApp. Here are some reasons why you might want to underline text in your conversations:

  • Highlighting crucial information: In a long message or a group chat, underlining keywords like addresses, phone numbers, or deadlines can make them immediately visible, avoiding misunderstandings and saving time.
  • Improving readabilityUnderlining can help structure the text and visually separate different sections, such as in a bulleted list or a brief summary.
  • Giving the message more impact: Want your event invitation or a call to action in a promotional message to not go unnoticed? Underline the keywords to capture the reader’s attention.
  • Expressing emotions: In combination with other formats like bold and italics, underlining can help express emotions such as surprise, irony, or emphasis, adding a touch of personality to your messages.

How to Underline on WhatsApp: The Methods

There are two main methods to underline on WhatsApp:

1. Unicode Special Characters

Unicode is a coding standard that assigns a unique code to every character, symbol, and emoji. Some of these special characters simulate the effect of underlining. To use them:

  1. Search for the characters: Perform an online search with keywords like “underline special characters” or “Unicode underline”. There are websites that offer a wide range of special characters, such as YayText.
  2. Copy and paste: Once you find the character you prefer, copy it and paste it into your WhatsApp message.

Advantages:

  • Ease of use: Just copy and paste the desired character.
  • Compatibility: Unicode special characters are generally supported by all devices and operating systems.

Disadvantages:

  • Aesthetic limitations: The visual effect may not be identical to standard underlining and can vary depending on the font used by the recipient.
  • Availability: Not all special characters are displayed correctly by all fonts.

2. Third-Party Apps

If using special characters seems cumbersome, you can opt for a third-party app that simplifies the process. Some apps, like BlueWords, offer the ability to underline text and then copy and paste it into WhatsApp. Here’s how it works:

  1. Download the app: Search for “BlueWords” or a similar app on your app store (App Store for iOS or Google Play Store for Android).
  2. Write the text: Open the app and enter the text you want to underline.
  3. Copy and paste: The app will generate the text formatted with the underline. Copy it and paste it into your WhatsApp message.

Advantages:

  • “True” underlining: The visual effect is generally more similar to standard underlining.
  • Additional features: Some apps offer advanced formatting options, such as the ability to customize the color or thickness of the underline.

Disadvantages:

  • Extra step: It requires using an external app.
  • Compatibility: Not all apps are available for all operating systems or devices.

WhatsApp offers several formatting options to customize your messages:

  • Bold: Enclose the text between two asterisks (*). Example: *Hello* becomes Hello.
  • Italics: Enclose the text between two underscores (_). Example: _Hello_ becomes Hello.
  • ~Strikethrough~: Enclose the text between two tildes (~). Example: ~Hello~ becomes ~Hello~.
  • Monospace: Enclose the text between three backticks (“`). Example: “`Hello“` becomes Hello.

You can also combine these formatting options with each other and with underlining to create even more dynamic and expressive messages.

Although WhatsApp does not offer a native feature to underline text, alternative solutions, such as using Unicode special characters or third-party apps, offer flexibility and customization options.

Unicode special characters are the most practical and immediate solution for most users. Copying and pasting these characters is a simple and fast process that does not require installing additional apps. Furthermore, they are generally supported by all devices and operating systems, ensuring maximum compatibility. However, the visual effect may not be identical to standard underlining and could vary depending on the font used by the recipient.

If you want a more accurate visual effect or need additional features, such as the ability to customize the color or thickness of the underline, you can consider using third-party apps like BlueWords. These apps provide a “true” underline and often include advanced formatting options. However, they require an extra step to download, install, and use the app, and may not be available for all operating systems.

Ultimately, the choice of the best method to underline on WhatsApp depends on your needs and preferences. If you are looking for a quick and simple solution, Unicode special characters are the ideal choice. If, on the other hand, you want a more professional and customized result, third-party apps offer more possibilities. The important thing is to communicate clearly and effectively, making the most of the available tools.
