An entry headword can have an unsorted part. The unsorted part serves to include in the headword certain linguistic information which helps to understand how to use the headword (i.e. what words the headword is usually used with, government model examples etc.) yet, if it were sorted, affects the position of the headword in the word list in an undesirable way.
The unsorted part is not displayed in the ABBYY Lingvo word list and is not used for translation. This means that when you add an unsorted part to an entry headword you do not create a new headword, and so you cannot use the tilde to denote both the headword and the unsorted part you added.
The unsorted part is displayed on the screen only in the entry headword. You should use braces to select a part of the dictionary text as the unsorted part of an entry headword. Example:
{to }have
иметь
Additionally, braces can be used in the headword or the body of the card to mark superscript or subscript.
for example, CO{[sub]}2{[/sub]}-Laser
