## Why the same mistakes keep happening

Most language errors are not about intelligence or education. They come from English itself: words that sound identical but are spelled differently (*their*, *there*, *they’re*), spellings borrowed from several languages at once, and fixed phrases that people learn by ear before they ever see them written. When a phrase is heard as “for all intensive purposes,” nothing in conversation corrects it. The error only shows up on the page.

Spellcheckers help with outright misspellings, but they are much weaker at catching a real word in the wrong place. *Loose* and *lose* are both correctly spelled, so a typo that swaps them sails through. That is why the guides in this section focus on **pairs, patterns and context**, not just lists.

## How to use this section

- **Proofreading something now?** Use the big table in [commonly confused words](https://erroneo.us/language/commonly-confused-words/) and search the page for the word you are unsure about.
- **Fixing a habit?** Each guide includes a memory trick. Pick the three errors you make most and learn only those.
- **Prescriptive vs. descriptive:** where dictionaries and style guides disagree (think *literally* or *irregardless*), we say so and link the sources, rather than pretending there is one rule.

Typos are a motor skill as much as a knowledge problem. If your errors come from fast fingers rather than uncertain spelling, deliberate practice helps: the free [typing trainer from allthingsN](https://allthingsn.com/typing/) has graded lessons for accuracy before speed.
