[12:46.90]Dictionary
[12:48.92]A dictionary is a reference book
[12:52.26]that focuses on defining words and phrases, including multiple meanings.
[12:59.57]The most frequently used dictionary is a language dictionary
[13:04.61]that includes the majority of frequently used words in a language.
[13:10.68]Language dictionaries are made for different types of users:
[13:16.44]scholars, office workers, schools, and second language learners.
[13:23.11]There are many competing dictionaries put out by different companies.
[13:29.44]Not only do they have different forms - paperback, hardback, and online editions
[13:37.12]- but they differ in other ways.
[13:39.78]Each company, for example, uses its own version of phonetic respelling
[13:46.97]based on the research done by its experts.
[13:50.93]Other differences between dictionaries show up in other features.
[13:57.19]Many dictionaries include their experts' guidance on grammar, usage, and the history of the language.
[14:06.51]Definitions differ slightly, and sample sentences may be the work of the editorial staff
[14:15.38]or taken from real-world usage, perhaps the first known written use.
