新型冠状病毒疫情（后简称“新冠疫情”）对世界各地的社会、政治、经济与生活等层面都产生了巨大影响。在此特殊的时代背景之下，为适应社会变化与政策的发展，大批与疫情发展密切相关的新造词应运而生，被广泛用于社会生活与日常交流的各个领域层面之上。

新词作为一般词汇的组成部分，能够及时地反映出社会不同时期的发展变化。新冠疫情期间产生的新造词反映了医疗科普与研究的层面对于精确表达的需求，帮助解读社会政策的变动，具有专业性强、时效性强、适用范围广等特点。

研究这部分新造词不仅要从来源与特点着手，亦要研究其内部的构词法与造词法原理。部分新词使用了说明法、比拟法与简缩法等多种造词法，以满足实际使用语境中的需求，帮助民众迅速理解新造词的含义，提高新造词的应用效率与传播速度。同时通过研究这部分新造词的构词法，了解新造词内部词素之间的关系。

新冠疫情期间特殊的社会背景与线上媒介平台的发展促进了新造词的涌现，同时受到了民众的广泛关注。新造词不仅在社会政策与舆论报道中扮演着重要的角色，也影响着民众的语言习惯，部分新造词的使用频率逐渐固定下来，甚至有形成新表达习惯的趋势。

自2022年11月起，国内的防疫政策产生了较大变动，新造词的使用与发展状况也受到了冲击。一部分新造词使用频率急剧降低，一部分新造词仍保持着较稳定的使用频率，将来可能成为固定词延续使用下来。因此，新冠疫情期间新造词在未来呈现怎样的发展趋势，都是值得探讨的问题。

Since the outbreak of the novel coronavirus in 2020, it has had a tremendous impact on social policies, economy, and daily life around the world. Under this special historical context, a large number of neologisms closely related to the pandemic situation have emerged and have been widely used in various aspects of social life and daily communication.

As a part of the general vocabulary, neologisms can promptly reflect the development and changes in society. The neologisms demonstrating strong professionalism in medical terminology; they help interpret changes in social policies, reveal changes in people's social habits, and have a wide range of applications. At the same time, a group of unique word formations has also emerged among the neologisms.

The study of neologisms related to the COVID-19 pandemic should also investigate their internal morphological and word-formation principles. Neologisms employ various word-formation methods such as description, analogy, and abbreviation, which improve the application efficiency of newly-created words. Studying the morphology of neologisms helps to further understand the relationships among the elements within these new words.

The generation of neologisms is influenced by special social backgrounds, the development of online media platforms, and public attention. Neologisms not only play a crucial role in social policies but also affect people's language habits and communicative expressions.

Since November 2022, there have been significant changes in epidemic prevention policies, and neologisms have been impacted by the changes in social policies. The usage frequency of some neologisms has dropped sharply, while others have maintained a relatively stable usage frequency and may become fixed terms in the future. The changes that neologisms will undergo in the future are all issues worth exploring.
