1	Wrong word

Prescience means “foresight,” and precedence means “priority of importance.”

Allegory, which refers to a symbolic meaning, is a spell checker's replacement for a misspelling of allergy.

Wrong-word errors can involve using a word with the wrong shade of meaning, a word with a completely wrong meaning, or a wrong preposition or word in an idiom. Selecting a word from a thesaurus without being certain of its meaning or allowing a spell checker to correct your spelling automatically can lead to wrong-word errors, so use these tools with care. If you have trouble with prepositions and idioms, memorize the standard usage. (See Chapter 29 on choosing the correct word, Chapter 30 on using spell checkers wisely, and Chapter 60 on using prepositions and idioms.)
