The longest literary word is in Sanskrit, and was listed in the Guinness Book of Records back when it was worth a damn, and before it turned into a picture book. I bought the book it featured in, and wrote about it here: What is the longest word of Sanskrit?
- Suryakanta. 1970. Varadāmbikā Pariṇaya Campū of Tirumalāmbā. Volume 79 of Chowkhamba Sanskrit studies. Varanasi: Caukhambā Saṃskṛta Sīrīj Āphis.
Tirumalamba is one of the few women writers in Sanskrit, writing in the early 16th century; the work is a Campu, a mixture of prose and verse, on the marriage of her contemporary king Achyuta Deva Raya. On the literary merits of Tirumalamba’s work, I’m not competent to speak, so I won’t; if anyone from Karnataka finds this and wants to chime in, they’re welcome to. If you do go googling for the text, btw, look for Tirumalamba, and not Varadambika Parinaya: there are lots of little annoying spelling variations for the book title.
“On the way, he passed through the Tuṇḍīra country.”
The chapter takes up 130 lines of English translation.
The reason it takes up 130 lines is, “the Tuṇḍīra country” is preceded by 25 accusative adjectives, and followed by three more.
Those adjectives, in turn, take up several lines, and correspond to one or two sentences each in English. One or two LONG sentences.
The monsterpiece, which is only first among equals, is adjective #12. It’s full of hyphens, so to my disappointment, I’m not going to destroy all the browsers in the world after all. I have taught myself enough Devanagari to type the word in, along with its translation and commentary.
I’m attaching a gif just in case, but after some initial confusion I think I did OK. The bad typography of the original was in fact helpful: the little gaps left between the vowels and consonants meant I could actually eyeball where the vowels were. The Unicode tables are missing one ligature of the edition (ङ्ग, which should look like a dotted ड्ग).
[CUT AND PASTE NOTE: Look at my original blog post: the Quora editor mangles the ligature.][EDIT: Oops—Quora actually gets the ligature right on my computer; YMMV]
So, the Tuṇḍīra country is, among other things:
In it, the distress, caused by thirst, to travellers was alleviated by clusters of rays of the bright eyes of the girls ; the rays that were shaming the currents of light, sweet  and cold water charged with the strong fragrance of cardamom, clove, saffron , camphor and musk and flowing out of the pitchers  (held in) the lotus-like hands of maidens (seated in) the beautiful water-sheds, made of the thick roots of Andropogon muricatus  mixed with marjoram, (and built near) the foot, covered with heaps of couch-like soft sand, of the clusters of newly sprouting  mango trees, which constantly darkened the intermediate space of the quarters, and which looked all the more charming on account of the trickling drops of the floral juice, which thus caused the delusion of a row of thick rainy clouds, densely filled with abundant nectar.
142. Lit. ‘their’; in the Skt. passage the noun बालिका has already occurred.
143. Lec. var. मधु-रस-शोतल for मधुर-शोतल.
144. पाटल also means the trumpet flower, but as a rule, saffron is the companion of camphor and musk in Sanskrit literature.
145. Galantikā means a pitcher and is so called because water flows out of it (गलत्यम्थोऽरुयाः गलन्तिका).
146. लवुलय —roots of Andropogon muricatus, commonly known as khas. Huts made of the sweet scented roots of Andropogon muricatus (khas ki taṭṭis) are a regular luxury in the summer season throughout India.
147. कन्दलत् in the fourth line goes with माकन्द-तरु in line 6. This custom of spreading cloth in front for a distinguished personage to treads upon still exists in India and is practiced on both formal and informal occasions. But now-a-days the colour of this cloth is not white but red. It starts from the entrance gate of a hall or a canopy and leads right up to the dais. पाकारि Lit. ‘the enemy of Pāka’, i.e. Indra.
