Looks up a selected word or phrase in WP, in the Oxford American Dictionary/Thesaurus that comes with OSX or in the fine, free Nisus Thesaurus.
While WP has its own dictionary and thesaurus, they do not provide or discuss definitions or usage. Linguists now know that meaning obtains in collocations, or phrases in common use. The sample phrases and the discussion offered by these two reference tools can become a substantial aid to good writing. OSX Lookup makes their use faster and more convenient in WP.
New in this version: supports both SheepShaver / WordPerfect installs: WPMacApp and SheepShaver-WP.
