Honorary means given as an honour, with no duties or pay attached. An honorary degree, honorary president, honorary member.
An honorary degree is awarded without the work and cannot be used to claim the qualification, though people do. An honorary post is unpaid, which is the older sense, and it is a different word from honourable.
