How to solve the problem that there is a big space between the letters of an English word in Word?

The issue of excessive spacing between letters within individual words in a Microsoft Word document is almost always a formatting problem, not a text entry error. The primary and most common cause is the accidental application of the "Expanded" character spacing setting. This is a font-level formatting attribute that increases the horizontal space between each character uniformly, which can make a word appear strangely stretched and disconnected. This setting is often triggered inadvertently by keyboard shortcuts, particularly Ctrl+Shift+> or through the Font dialog box (Advanced tab). A secondary, though less frequent, cause in justified text alignment is that Word may be attempting to stretch text to fill a line by adding space between characters, rather than just between words, especially if hyphenation is off or the paragraph contains very long words.

The definitive solution is to reset the character spacing to its default state. First, select the affected text. You can do this by dragging your cursor over the problematic word or paragraph. Then, open the Font dialog box. The most direct method is to press Ctrl+D on your keyboard. Within this dialog, navigate to the "Advanced" tab. Locate the "Spacing" dropdown menu, which will likely be set to "Expanded" with a corresponding value in the "By" box next to it. Change this dropdown selection back to "Normal" and ensure the "By" value is cleared or set to zero. Click "OK" to apply the change; the text should immediately revert to standard letter spacing. If the problem persists throughout the entire document, you can select all text (Ctrl+A) before performing this reset.

If adjusting character spacing does not resolve the issue, you must investigate other formatting influences. Examine the paragraph alignment: fully justified text (Ctrl+J) can create visual spacing issues, especially in narrow columns. Switching to left alignment (Ctrl+L) is a useful diagnostic step. Furthermore, check for any manually inserted spaces between letters, which can occur if someone has used the spacebar in an attempt to visually separate characters. To reveal these, toggle on the formatting marks by clicking the paragraph symbol (¶) in the Home tab or pressing Ctrl+Shift+8. This will display dots between words for regular spaces, allowing you to see and delete any erroneous ones within a word. For persistent, document-wide issues, consider that the problem may be tied to a specific Style. Modify the underlying Style (e.g., Normal Style) by right-clicking it in the Styles gallery, selecting "Modify," and then using the Format button to access the Font settings and ensure spacing is set to Normal, thereby fixing all text based on that style at once.
