History
OS X's progenitor,
OPENSTEP (and
NEXTSTEP) provided similar functionality, called Digital Webster, providing

and
thesaurus definitions from
Webster's Ninth New Collegiate Dictionary and Webster's Collegiate Thesaurus (termed the "First Digital Edition"). OPENSTEP Services provide lookup from all applications.
Dictionary was first introduced with
Mac OS X v10.4 "Tiger" and provided definitions from the ''
New Oxford American Dictionary, 2nd Edition''. With
Mac OS X 10.7 "Lion", Dictionary was updated to the Third Edition of the ''New Oxford American Dictionary'' and the British ''
Oxford Dictionary of English'' was added.
Functionality
Words can be entered in the search bar by just typing the first few letters. The application will perform an incremental search to show any matching headwords or forms and will try to bypass spelling errors. Clicking on any word in a definition searches for that word in the dictionary again. Almost any word is clickable, except the pronunciations in phonetic characters and numerals.
The Preferences allow a user to select from three different pronunciation schemes, either US English (Diacritical or
IPA), or British English (IPA).
The dictionary and thesaurus in Dictionary are in an

Quick access
* In applications which support "Services", there is an option in the application menu (for example, Safari>Services>Look up in Dictionary) which brings up the Dictionary application and displays the definition of a selected word. The same option appears in the
contextual menu after a Control-click on the selected word.
* The key combination can be used in
Cocoa applications which display text – it brings up a small contextual menu-like definition or synonym of the word under the
cursor.
* As of
Mac OS X Lion, a three finger tap on the trackpad (either the built-in
MacBook trackpad or the
Magic Trackpad) has the same effect as the shortcut.
* In applications which support the ability of the user to drag selected text, it is possible to select a word and drop it onto the icon of the Dictionary application in the
Dock.
*
Dashboard includes a
widget for accessing the Dictionary application.
* macOS catches any queries to the
dict://
URI scheme, say from a web browser, and routes them back to the Dictionary application.
* Since
OS X Leopard, the dictionary has become tightly integrated with
Spotlight, allowing users to view definitions from immediately within the system search.
