# List of commonly misused English words

This is a list of English words that are thought to be commonly misused. It is meant to include only words whose misuse is deprecated by most usage writers, editors, and professional grammarians defining the norms of Standard English. It is possible that some of the meanings marked non-standard may pass into Standard English in the future, but at this time all of the following non-standard phrases are likely to be marked as incorrect by English teachers or changed by editors if used in a work submitted for publication, where adherence to the conventions of Standard English is normally expected. Some of the examples are homonyms or pairs of similarly spelled words that are often confused.
The words listed below are frequently used in ways that major English dictionaries do not condone in any definition. See List of English words with disputed usage for words that are used in ways that are deprecated by some usage writers but are condoned by some dictionaries. There may be regional variations in grammar, orthography, and word-use, especially between different English-speaking countries. Such differences are not classified normatively as non-standard or "incorrect" once they have gained widespread acceptance in a particular country.

** Standard: The board of directors developed an algorithm for choosing the company's new president from among the remaining candidates.
