Upsilon Symbol: Pronunciation and How to type it?

The upsilon symbol (lowercase υ and uppercase Υ) is the 20th letter in the Greek alphabet and the sixth letter in the Phoenician alphabet.

The delta upsilon (ΔΥ) is between the tau and phi letter in the Greek alphabet, used in particle physics to represent the meson particles, composed of a bottom quark and its antiparticle.

The Greek letter upsilon is pronounced like the “ee” in “see” in Modern Greek. However, it was pronounced like the French “u” or the German “ü” in ancient Greek. The symbol Υ/υ represents the sound of upsilon in the International Phonetic Alphabet.

You can use the keyboard shortcut Alt + X to type the upsilon letter. To get the lowercase version of the symbol, type 03C5 and press Alt + X. To get the uppercase version, type 03A5 and press Alt + X.

Using Microsoft Word, you can easily insert the Υ/υ symbol using the alt code. While this method typically works for numeric keyboards, it can still be done on laptops with a NumLock key.

To insert the Υ/υ symbol, use the alt code 933/965. While holding the Alt key, then type 933/965 on the numeric keyboard. The Alt code will then be converted into upsilon.

Alt + 933 = Υ
Alt + 965 = υ


An alternative method for typing the delta upsilon (ΔΥ) on Microsoft Windows is using the Character Map tool. To access it, search for “Character Map” in the search bar and press Enter, which will prompt a pop-up menu.

If you find that the “Υ/υ” alternative code isn’t working for you when trying to insert the mirror Υ/υ symbol, don’t worry! An additional option is available to you in the form of a shortcut code. This particular code is designed to be used on a standard keyboard that lacks a numeric keypad.

Enter 03A5/03C5 within your Word document to utilize the upsilon keyboard shortcut. Then, press the Alt and X keys simultaneously. This action will cause the code you’ve entered to be updated automatically and display the desired symbol.

03A5 + Alt-X = Υ
03C5 + Alt-X = υ

How to Type Upsilon Sign in Mac?

If you’re using a Mac keyboard, you may have noticed that the “Υ/υ” key is not readily available. However, a simple workaround allows you to insert the symbol using your keyboard preferences.

To get started, open your Keyboard Preferences, which can be accessed via the Mac menu by selecting “System Preferences” and then “Keyboard” or by using the Spotlight search function to locate “Keyboard Preferences.” Once you’re there, navigate to the “Input Sources” tab.

In the list of input sources, look for the “U.S.” option and click on it. Then, check the box next to “Show input menu in the menu bar,” which will add a flag icon to the top menu bar. You can use this icon to switch between different input sources.

Next, select “Show Emoji & Symbols” from the input menu in the top menu bar. This will open the Emoji & Symbols window. In the search field at the top of this window, type “UPSILON.” This action will prompt the “Υ/υ” symbol to appear.

Finally, double-click the “Υ/υ” symbol to insert it into your document. That’s all there is to it!


There are multiple methods if you need to type the upsilon symbol on various platforms and devices. For instance, you can locate it on Windows using the Unicode code “03A5” or “03C5” and pressing the Alt+X keys. On Mac, the symbol can be accessed via the Emoji and Symbols feature by pressing “Control + Command + Space” and searching for it.
