What does the word honorary mean?

It means that a title has been granted not because the person has earned it in the ordinary way, but because of some other accomplishment they have done. For example, while normally to be given the degree of Doctor by a University, you have to write a thesis, pass exams, etc. sometimes they will give an "honorary Doctorate" to someone because they were the mayor, or started a charity organization, or did something else quite unrelated to academic achievement.

The same applies to being made an "honorary citizen" (you don't actually have to go through the procedure to make yourself a citizen) or "honorary member" (you don't have to apply for membership, pay dues, or do anything else that ordinary members do)
