Some confusing words are homophones. They sound alike but have different meanings.

Examples include:

• Right / write
• Here / hear
• Weather / whether

Other words have similar spellings but different meanings.

Modern English also contains many words with overlapping meanings. This can create confusion even when their spellings differ.
