NOTE: Documentation applies to Phraseology 2.0 or greater, shipping Feb. 2014!
Phraseology can highlight parts of speech as you type.
Highlighting is based on linguistic analysis algorithms built into iOS, and is currently available only for the English language.
NOTE: The linguistic analysis tools are sophisticated, and do an excellent job of identifying parts of speech when words are used in appropriate contexts – but the analysis is not perfect and should be expected to make erroneous identifications from time to time.
To use highlighting, tap the highlighting options button (concentric circles) in the sidebar, and tap the parts of speech to toggle highlighting on and off for that part of speech. Use the "Clear All" button to disable all highlighting.
