celebrate是什么意思
Affixes Most Frequently Ud in English. An affix（词缀）is a letter or group of letters, for example ‘un-’or ‘-y’, which is added to either the beginning or the end of a word in order to form a different word . An affix includes prefix (added to the beginning of the word,前缀）and suffix（added to the end of the word,后缀). When a prefix is added to a word, the word often has a new meaning. For example, unhappy, dishonest, incredible. When a suffix is attached to a word, the word often has a new part of speech（词性）. For example, friendly, quickly.
