Final answer:
The English dictionary has evolved to encompass over 600,000 recognized words, with many being technical and scientific terms. Dictionaries document the changing vocabulary, including the meanings and applications of words, and have expanded into electronic formats for easy updating and access.
Step-by-step explanation:
The English dictionary has evolved to include over 600,000 recognized words, according to the OED (Oxford English Dictionary). Within this vast lexicon, there are technical and scientific words that are specialized and may not be frequently encountered outside of their specific contexts. For instance, while there are over 300,000 types of beetles, there isn't a language that has a separate term for each kind.
Dictionaries serve as a record of a language's vocabulary, including words from many areas of life and knowledge. Technological advancements have allowed for the creation of electronic dictionaries and smartphone apps, which can easily be updated and accessed to reflect new changes in language use. These resources can include a wide array of subjects, such as scientific and technical information. An example from the United States Patent Office and Trademark website mentions its own scientific and technical resource center, underscoring the extent and specialty of vocabulary that may be included in dictionaries.
Words in the English language can be simple, double, or even multiple in form, and their meanings can change over time. The imperative role of dictionaries is to document these linguistic evolutions and ensure effective communication.
