Why won’t my words capitalize correctly?
When every word refuses to start with a capital letter—or starts capitalizing erratically—it’s usually one of three things: a keyboard setting, an app-level AutoCorrect rule, or a font limitation. Microsoft Word, Excel, Google Docs, and even iOS keyboards have built-in “AutoCorrect” features that can force lowercase, UPPERCASE, or Title Case without warning. As of 2026, most major platforms still rely on these legacy behaviors, though some have added AI-driven suggestions. A locked Caps Lock key or a corrupted font cache can also make every character appear uppercase, mimicking capitalization errors.
