Final answer:
A position that has no salary is called 'honorary'. It is a title or role given as a form of honor without payment for services rendered, different from 'honorable', which describes something worthy of respect.
Step-by-step explanation:
A post which carries no salary is typically referred to as 'honorary' rather than 'honorable'. An honorary position is one that is given as an honor, without the usual requirements or functions, and often without payment. For example, someone may be given the honorary title of lieutenant, but this does not mean they would receive a salary. Instead, it's a recognition of their status or contribution, possibly accompanied by certain privileges or expenses covered, but not a traditional wage or salary.
The phrase 'honored with the post' could be used to describe someone receiving a high-ranking position because of their merit or contributions. An example from history is Toussaint Louver Ture, who stated that in his service to the Republic, he did not claim a salary, acting instead with 'honor, fidelity, and integrity'.
