Our friend and colleague Omer has sent the following comments:
(a) I tend to agree with Tim’s view about a ‘military’ or ‘camp ‘ language , w r to the language of the Orcs. As you might probably know, Urdu- our Pakistani national language – was born in the medieval times, during the early Muslim conquests of India by several invading tribes from the North and North West eg the Turks, Afghans, Mongols/Muguls etc. These invaders used to garrison their mercenary armies of mixed Central Asia/Afghan types (with a small number of local Hindi mercenaries too) in special camps, usually outside the main cities like Delhi and Lahore; and since all sorts of commodities etc were to be provided to these warriors, by local merchants and farmers etc, a sort of mixed patois developed, which included a Hindi base with Turkish and Persian and Pushto/Afghan words, later on also a smattering of Arabic. This developed into a proper camp language or ‘lingua franca’ and was designated as ‘Urdu’ in fact a Turkish word meaning ‘camp’. Compared to Hindi and its associate languages and dialects, it was a somewhat harsh-sounding language, with more gutturals (which become flattened out in Hindi) and resembled, in its early manifestation, languages such as Gaelic or German. Over time, as the Hindi influence grew , the language became softer and more refined (as we note in the 18th-19th centuries with the growth of Urdu poetry in Delhi and Lucknow) — but the essential and basic ‘rough and ready’ character still remains in the common Urdu (Urdu i Aaama or the Ordinary Camp) vis a vis the later high/refined Urdu (Urdu i Mualla, or the Exalted Camp). I always imagine Orcish to be somewhat like the early rough Urdu. A hodge-podge language of all the tribes between the Indus and the Aral Sea.
(b) the comments about Shelob and the bottled starlight/Elvish light brings to mind an old folk tale here in this region, of ‘Nikka Pai” a younger son/brother of a farmer, who has to go down to the Underworld/Hades to rescue his elder brother from the demons who have taken him , in order to fulfill a promise to their parents. As he is a good-hearted and pure-spirited lad, and loyal to his elder brother and devoted/obedient to his parents, of course, Divine Help comes his way; he meets a saint or mystic ‘Baba’ (elder/old man) who gives him a mystic phial, of ‘Heavenly light’ . This has the power to bring positive force/energy to the owner/user– in the Underworld, we are told, all positive energy/force is sucked away, and people become dull and even lose their colour, they become ‘grey’ like the dead ones; but the Heavenly light phial can bring back this positive energy and drive away those demons and negative forces that thrive in the darkness. Strange echoes of both this Tolkien incident/scene and of the Dementors, in the Harry Potter books by JK Rowling — in fact, my youngest son, Hissam, reminded me of this, as he was reading Harry Potter and had of course listened to this story in his childhood.
