Primary love language (criterion)

Question structure: OPTSQ

The Five Love Languages is the title of a book by Gary Chapman (author) from which these are taken.

• Words of affirmation
  This language uses words to affirm other people.
• Quality time
  This language is all about giving the other person your undivided attention.
• Receiving gifts
  For some people, receiving a heartfelt gift is what makes them feel most loved.
• Acts of service
  For these people, actions speak louder than words.
• Physical touch
  To this person, nothing speaks more deeply than appropriate physical touch.
• None of these

The list is taken from the book. There may be other fuller lists that include these. “None of these” could perhaps be expanded in a sub-question.
