noun, plural online dictionaries.
a dictionary that is available on the Internet or World Wide Web and accessed through a web browser
using a computer or a mobile device, primarily by typing a query term into a search box on the site. Online dictionaries like Dictionary.com
offer immediate, direct access through large databases to a word's spelling and meanings, plus a host of ancillary information, including its variant spellings, pronunciation
, inflected forms, origin, and derived forms, as well as supplementary notes on matters of interest or concern about how the word
is used: Some people think online dictionaries will make print dictionaries obsolete.
