There are two not very well-known theories about the relationship between HUMANS and HUMOUR or HUMOR. These theories seem to have been expounded by British and American English speaking communities. Although having some similarities, these theories reach different conclusions.
According to the first theory as postulated by British English speaking people the word" humour" is derived from the word" human" and HUM denotes human. As humour, to all intents and purposes is an exclusive human domain so far, (research may prove otherwise and one day we may associate Giraffe with humor of highest order), it must relate to humans. There is some weight in the argument. Another argument providing support to the theory is the fact that human and humor share common beginning in the form of words h, u and m. Yet, another argument concerns the composition of the word HUMOUR . According to them after dissection of the word equally in two portions it will appear as HUM & OUR, interpreting that HUM, i.e. humans say that it (humour) is ours, i.e. it has come from them. The second theory that finds support among the American English speaking people who differ in the spelling of the word humour, (as also in real humour) and take it as humor, present an entirely different argument. According to them, the dissection of the word in equal is not possible with humor, but even if the word is dissected on the basis of the first three words and two remaining words it will appear as HUM & OR and argue that OR represents the word “origin” and while agreeing that HUM represents human, they stipulate that the real interpretation of HUMOR is that the origin of human is humor . It is very difficult to say how God will respond to this theory and one has to wait more for that. Whatever the merits and demerits of the two theories just like the “ Egg and Hen” theory we shall have to wait, but one is justified in assuming that human and humour/ humor has a parent child relationship, but it is still to be decided who is the parent and who is the child? Disclaimmer: All those who try to find the basis/ truth of the above theories will do that at his own risk of failure without in any way making judgement on the genuineness of the article's contents and the efforts going into it.
