What Is a Prefix?
A prefix is a letter or group of letters that are added to the beginning of a word to alter its meaning. For example, the prefix “co-” means “together.” Therefore, cooperation refers to “working together.”
I was not used to the level of cooperation but found it extremely beneficial.
A prefix is a subcategory of affixes, which are letters that are added to a word to change its meaning.
Affixes can be either inflectional or derivational. An inflection affix is added to a word to indicate grammatical information (such as tense and number) while maintaining the word’s core meaning (e.g., bird vs. birds). Derivational affixes can completely change the meaning or grammatical role of a word (e.g., interesting vs. interestingly).
In English, suffixes can be both inflectional or derivational, while prefixes solely undertake a derivational role.
Keep In Mind
The word prefix can also function as a verb that means “to fix or appoint beforehand.”
- She decided to prefix the presentation with a quick recap of her school’s recent accomplishments.
