You apply a custom ligature setting to a paragraph in Word, but when you update the paragraph style, the ligatures snap back to the default. This happens because Word stores font-level settings like ligatures separately from paragraph style definitions, and the style update overwrites the manual font formatting. This article explains the cause of this behavior and provides a step-by-step method to lock your ligature choice so it survives style updates.
Key Takeaways: Ligature Persistence After Style Updates
- Home > Styles > Modify Style > Format > Font > Advanced > Ligatures: Set your preferred ligature level inside the style definition so it is not overwritten by manual formatting.
- Keyboard shortcut Ctrl+Shift+N to reapply Normal style: Resets manual font overrides and can accidentally remove ligatures if the style itself does not define them.
- Home > Styles > Manage Styles > Set Defaults: Changes the baseline ligature setting for all new documents based on the active template.
Why Ligatures Revert When You Update a Paragraph Style
Ligatures are decorative character combinations where two or more letters are joined into a single glyph. Examples include fi, fl, and ffi. Word offers five ligature levels: None, Standard, Standard + Contextual, Historical, and Discretionary. The default for most fonts is Standard.
When you apply a ligature setting to a paragraph using the Font dialog, Word treats this as direct formatting. A paragraph style, on the other hand, stores a separate set of font properties. When you right-click a style and choose Update to Match Selection, Word copies the current paragraph formatting into the style definition. However, the ligature setting from the Font dialog is not always included in that copy operation because ligatures are considered a font advanced property. Word’s default behavior is to ignore font advanced properties during a style update, so the style reverts to its previous ligature setting.
Steps to Keep Ligatures After a Style Update
The fix is to embed the ligature setting directly into the paragraph style definition. Do not rely on manual font formatting. Follow these steps.
- Open the Modify Style dialog
On the Home tab, open the Styles pane by clicking the small arrow in the bottom-right corner of the Styles group. Right-click the paragraph style you want to change and choose Modify. - Access the font advanced properties
In the Modify Style dialog, click the Format button in the bottom-left corner and select Font. In the Font dialog, click the Advanced tab. - Set the ligature level
Find the Ligatures dropdown. Select the level you want: None, Standard, Standard + Contextual, Historical, or Discretionary. Click OK to close the Font dialog. - Set style update behavior
Back in the Modify Style dialog, check the option Automatically update. This tells Word that any future direct formatting changes you apply to a paragraph using this style will update the style definition. Click OK to save. - Apply the style to existing text
Select all paragraphs that should use the ligature setting. Click the style name in the Styles pane to reapply it. The ligature level you set in the style definition now takes effect.
Alternative Method: Set Ligatures via the Template
If you want all new documents to use a specific ligature setting by default, modify the Normal template. Open Word and create a blank document. Click Home > Styles > Manage Styles (the icon with a checkmark and a pen). In the Manage Styles dialog, click the Set Defaults tab. Under Font, click Advanced and set the Ligatures dropdown to your preference. Check New documents based on this template and click OK. Every new document will now use that ligature level as the default.
If Ligatures Still Revert After the Style Fix
Word keeps the ligature setting but the font does not support it
Not all fonts include ligature glyphs. If you choose Historical or Discretionary ligatures but the font lacks those glyphs, Word silently falls back to Standard ligatures. Check the font specification or use a font like Gabriola or Adobe Caslon Pro that supports discretionary ligatures.
Another style overrides your ligature setting
A paragraph can inherit formatting from multiple styles. If you apply a style that is based on another style, the base style’s ligature setting can override yours. In the Modify Style dialog, check the Style based on field. If it shows a base style, modify that base style to include the ligature setting, or change the Style based on to (no style).
Ligatures disappear after reopening the document
This usually happens when you open the document in an older version of Word or a different application that does not support advanced ligature settings. Save the document in the .docx format and avoid compatibility mode. On the File menu, click Info > Convert if the document bar shows Compatibility Mode.
Ligature Setting Methods: Style Definition vs Direct Formatting
| Item | Style Definition | Direct Formatting |
|---|---|---|
| Persistence after style update | Survives | Reverts to style default |
| Setup location | Modify Style > Format > Font > Advanced | Home > Font > Advanced |
| Affected paragraphs | All paragraphs using that style | Only selected paragraphs |
| Ease of global change | Change one style, all text updates | Must select and change each paragraph |
Use the style definition method when you need the ligature setting to survive future style updates. Use direct formatting only for one-off decorative text that you do not plan to update later.
You can now apply custom ligatures to any paragraph style and update that style without losing the ligature setting. The key is to set the ligature level inside the style definition rather than as direct formatting. For a more advanced workflow, create a separate character style that only contains the ligature setting and apply it alongside your paragraph style using the Style Separator feature.
