By definition, this is honesty, fairness, and integrity in one's beliefs and actions.
What does that mean?
One of the cornerstones of honor is esteem and respect for every living creature, If one does not respect someone, one has little reason other than one's own personal beliefs to treat a person with fairness or integrity.
One must also bear respect for oneself. If one does not respect oneself, then one has no reason to keep oneself to an honorable standard.
Breaking this down even further, then, one must explain what it is to act with integrity.
Integrity is a standard to which one holds all of their actions. This standard must be adhered to at all times, and as a result consistency is achieved, such that one's treatment of all creatures, within reasonable bounds, is equivalent.
Fairness is very much related to integrity; when one is consistent in the way which all creatures must be treated, one can say that they act fairly toward all creatures.
However, that is not the entirety of fairness. Fairness can also contradict with the goal of consistency, however, as fairness is not precisely the act of treating all creatures the same. Instead, fairness takes into consideration all aspects of the situation and applies appropriate judgement. To be fair to one person, one may need to take into consideration a number of factors which are not present for another, yielding an entirely different action and result.
There is also the matter of honesty. Acting with fairness and integrity, the honorable person should of course be honest to all. Honesty therefore, must be defined, as it is one of the key tenets of honor.
Honesty is more than simply electing not to lie. One can tell the complete truth in all things, and still lead a person to an inaccurate conclusion. Therefore, honesty is instead the intention to not mislead any being into wrong thinking. This can be conveyed through actions or words.
How does honor apply in combat?
To review, honor is a matter of treating all people, even enemies, with respect and esteem. In many ways, therefore, it can be said that to act less than honestly is still honorable; for example, a feint in combat would lead an opponent into wrongful thinking, but to abstain from using a specific technique because it is dishonest does not show respect to your opponent's abilities.
Therefore, honor in combat may not be entirely synonymous with honesty, as treating an enemy with appropriate respect includes the important point that you must never underestimate an opponent. To underestimate any person is to be disrespectful.
That is not to say that honor is simply the drive to win at all costs; however, and using techniques which do not fall in line with one's own morality would conflict with honor directly.
However, if one were to act in a way that was dishonest in combat, one may still be honorable, as this displays respect for the opponent's skill and strength.
Next we must address that honor is not only actions, but beliefs. To treat a person with respect, one must not only act in a respectful fashion, but to believe that they are worthy of respect. This comes back to the basis of honor, both in combat and out.
To elaborate, this means that one must not underestimate one's allies, and must instead respect what they are capable of. One should also respect others' beliefs and actions, whether or not those beliefs or actions conflict with those one may hold, themselves.
In closing, honor is based upon respect for all creatures. To be honorable is not only to act respectful, but also to hold others in approprie esteem. To act respectful, one should be honest in both actions and words, seeking not to mislead others into wrongful thought. To maintain one's own honor, one should act with integrity, which is to say that one's behaviour should be consistent as possible. Fairness dictates that one may not treat every creature in the exact same fashion, as circumstances may vary dramatically, but to treat each creature in equivalent fashion based upon the circumstances.
