Well, if you insist. In fact, there is likely no alienation at all intended by the author, and I have no clue what is sought by the 'language and structure of alienation' term.
In response to numerous claims by admiring critics of the newly-published poem that it was about the collapse of political systems, Eliot said the poem was merely "a piece of rhythmical grumbling". Some also said it concerned the disillusionment of the generation, to which Eliot replied, "Nonsense!".
He also said the poem was inspired by his readings about the Holy Grail, especially J. L. Weston's book From Ritual to Romance, and two volumes from The Golden Bough by James Frazer (Adonis, Attis, Osiris). The Holy Grail we see so often nowadays as either the chalice used by Christ at the Last Supper, or as Mary Magdalene carrying Christ's love child are not the same as the Grail TSE discusses at all.
Turns out the original Grail legend had to do with a Waste Land where all animals and crops have died because waters have dried up. The desolation is somehow related to the sickness of their old ruler, the Fisher King. The object of the Grail quest is to revive the ailing king and restore the land's vigor. The hero knight was required for some reason to ask for the meaning of the Cup and Bleeding Lance. If he remembered to make that inquiry, the king would magically be cured and waters rise again, restoring crops in the process.
Similarly, in the Golden Bough, the gods of vegetation (a Phoenician, a Phrygian and an Egyptian) experienced death and resurrection which represented the seasonal decay and revival of nature. Fairly silly stuff, but not my fault. Earlier cultures had strange beliefs. Not to say lots of our current beliefs are much wiser, no.
Still, if required, we will have to manufacture some alienation materials by whole cloth. If they are purely fictional, we can surely be forgiven since the assignment itself is poppycock (as TSE himself told us).
There are references to Dante's Inferno, so surely one can infer that Hell is a place of alienation, right?
Tiresias might also be used for that response, having been both a man and a woman. He is both familiar with and alienated from each sex, I mean.

What else ... In the second part, we see unhappiness with marriage. In part three, the secretary and her pushy friend. In part five, we find the Hindu wisdom of how to escape desolation through generosity and self control.
Well, that is enough for the moment. I have errands to run and miles to go before my nap. Hopefully this will give you some ideas to help you make further interpretations on your own. Click on the earlier links and look for synopses of the various parts, for example.

Perhaps someone else can guess what is desired by the language and structure query, but it is too vague for me, sorry.
