Novel coronavirus's English is coronavirus pneumonia-19.

English vocabulary is huge (about 990 thousand words), but to estimate the specific figures, we must first judge which words can be counted as it. New words in the fields of medicine, science and technology are constantly emerging, some of which have entered the daily language of the public, and some are only used in a small range of people. Foreign language words brought by immigrant groups tend to blend into the English-speaking society.

Precautions:

The Oxford English Dictionary (Second Edition) contains more than 500,000 entries, and the standard is relatively loose: "It includes standard words in literature and daily conversation, whether contemporary, outdated or archaic, as well as major scientific and technological words and a large number of dialects and slang." ?

Since the popularization of electronic computers, many words related to this category have entered the public life; In addition, many new words related to telecommunication technology are composed of affixes.
