前缀
(grammar) a letter or a set of letters that are added to the beginning of a word to alter its meaning and make a new word
A prefix is a type of affix that is added to the beginning of a base word or root to modify its meaning. Prefixes can change the meaning of the word in various ways, such as indicating negation, repetition, or degree. For example, the prefix "un-" can be added to the word "happy" to form "unhappy", which means not happy. Other examples include "redo", where the prefix "re-" indicates doing something again, and "preview", where "pre-" means before. Prefixes are important in word formation, allowing for the creation of new words and the expansion of vocabulary in many languages.
