In the Navigation Pane, click Lexicon, and then click Lexicon Edit.
In the Entries pane, click the entry that has the allomorphs you will merge.
In the Entry pane, under Allomorphs, click the Stem Allomorph or Affix Allomorph field label that has the allomorph that you will merge into another allomorph, or into the lexeme form.
The menu button (
) appears.
Click the menu button, and then select Merge Allomorph into.
The Merge Allomorph dialog box appears.
In the Allomorphs pane, select the allomorph or lexeme form into which you will merge the current allomorph (indicated in the information area at the bottom of the dialog box).
If the description of the merge describes the correct allomorphs or form and the intended merge direction, click Merge.
The form is appended to the form of the receiving allomorph or to the lexeme form. The Morph Type and Environment(s) of the receiving allomorph or form are retained, but those of the merged allomorph are not retained.
Further, any interlinearized words that use the allomorph that you merged now use the allomorph or lexeme form into which you merged the allomorph.
Edit the allomorph or lexeme form, if necessary.
