In the Navigation Pane click Texts & Words, and then select Word Analyses.
In the Wordforms pane, click a word to select it.
On the Parser menu, click Clear Current Parser Analyses.
Clear Current Parser Analyses does the following for the selected word:
Parse result fields change from Successful or Failure to Untested.
Analyses set to User Opinion Unknown are deleted. Analyses that reflect user involvement, such as those set to User Disapproved, are not deleted.
The numerical value in the Predicted Analyses column (if displayed in the Wordforms pane) changes to 0 (zero) indicating that there are currently no successful parses for the word.
The Remove Parser-approved analyses utility on the Tools menu does the same for the entire word list.
Use this Parser menu command or the utility when you think there are problems of any kind with the analyses that are returned by the parser, or when you simply want to remove parser-suggested analyses.
Then, you can use Parse Current Word or Reparse all words to learn if Failure or Successful appears in the Parse result fields and if additional analyses are proposed by the selected parser.
