When you have a word that has a qualifier (i.e. something in brackets that helps define, or qualify it), you will normally need to link to the version without a qualifier, or to the word(s) which have the related qualifiers.
For example, in FR we have this year (emphatic form). When a student sees this, they will naturally ask themselves, "OK, that's the emphatic form, but what then is the non-emphatic form?". Therefore you should link with a "see also" type link to the other form. In this case, it links to this year.
Other examples:
- white (masculine) links with a "see also" to white (feminine)
- some (plural) links with a "see also" to some (masculine) and some (feminine)
- times (number of repetitions) links with a "see also" to time (clock)
