Capitalization in Quotations
The set of conventions governing when to keep, change, or silently bracket the first letter of a quoted passage.
When a writer folds a quotation into a sentence, the original's capitalization does not always match the new grammar. English style guides handle the mismatch differently. MLA and Chicago allow small changes — capitalizing or lowercasing the first letter — to be made silently when the change is only cosmetic; strict legal citation requires the changed letter to be bracketed ('[T]he defendant argued'). APA sits in between.
The core principle is that the change must not alter meaning. Lowercasing 'The' at the start of a sentence to fit it inside a running clause is invisible; changing a proper noun's capitalization to make the quotation flow would be a distortion. When in doubt, use square brackets to show the reader exactly what has been changed.
The mirror problem arises when a quotation begins mid-sentence but must be introduced as if it were a complete thought. Legal writers often capitalise inside brackets — '"[T]he rule is well established"' — precisely because their readers will check. In gentler house styles, the same sentence might appear as '"the rule is well established"' with no bracket, on the theory that the reader can see from context that the quotation was extracted.
Common mistake: silently changing capitalisation in a legal or heavily-cited academic context where readers expect brackets. When the audience is trained to notice, invisible edits look like carelessness or worse.
