# lakṣaṇa (लक्षण) > Canonical version of this page: https://nighantu.ageayurveda.com/lexicon/lakshana/ An Ayurvedic technical term, rendered into English in 6 different ways. The renderings do not agree, and the difference between them changes what the term is taken to mean. ## Identification | Field | Value | | --- | --- | | Transliteration | lakṣaṇa | | Devanagari | लक्षण | | Also written | lakṣaṇam, lakshan, lakhana, liṅga (as declared synonym) | | Category, as gathered | nidana | | Grouped under | Causation and the course of disease | | Classical citations | 5 | | Citations checked | 2026-10-08 | ## How it is translated, and whether the translation holds Each rendering is given with the source that uses it. The assessment is ours. ### Characteristic feature WHO international standard terminologies on Ayurveda (2022) · ITA-4.5.5, third gloss in the synonym list (position-aligned to lakṣaṇam) · standards body WHO gives lakṣaṇam no code of its own; it sits inside the ITA-4.5.5 'Signs and symptoms' synonym block with six other words. The alignment of this particular gloss to this particular term is read off the PDF table layout and is not labelled.

Anyone crosswalking lakṣaṇa to WHO gets ITA-4.5.5 and cannot distinguish it from liṅga, cihna, ākṛti, saṃsthāna, vyañjana or rūpa.

Hence, that by which anything else is seen is called 'Lakshana.' Charaka Samhita, tr. Avinash Chandra Kaviratna (public domain), translator's footnote · Nidana Sthanam, Lesson I, footnote to the synonym verse · public-domain translation The only public-domain English etymology of the term I located. Note what it makes lakṣaṇa: an instrument of observation, 'that by which anything else is seen', which is why the word can serve in a definition (a defining mark) as well as in a symptom list. ### sign and symptoms Charak Samhita New Edition (carakasamhitaonline.com) · Ca. Ni. 1.9 synonym list · modern scholarly edition CC BY-NC-SA 4.0 comparator; treats lakṣaṇa as undifferentiated from the rest of the list. ### signs and symptoms (as a synonym of rupa) easyayurveda.com rendering of Ashtanga Hridaya Ni. 1.5 and Madhava Nidana 1.7 · AH Ni. 1.5; MN 1.7 · modern textbook website · our paraphrase of the source, not its words PARAPHRASE of the comparator's treatment, not a quoted head term: both pages list lakṣaṇa among the synonyms of rūpa without glossing it separately. Recorded to document that the textbook tradition does not differentiate it either. ### defining characteristic (as used in the titles of classical chapters) Madhava Nidana chapter 1 title, 'Pañca Nidāna Lakṣaṇa' · MN chapter 1 title, as printed on the retrieved page · classical text title · our paraphrase of the source, not its words PARAPHRASE, and the reason this record exists. In the chapter title lakṣaṇa cannot mean 'symptom': the chapter is about the definitions of the five, not about anyone's symptoms. No standard records this sense. ## The classical passages ### Charaka Samhita Nidāna Sthāna 1 (Jvara Nidāna):9, checked against the source > प्रादुर्भूतलक्षणं पुनर्लिङ्गम्| तत्र लिङ्गमाकृतिर्लक्षणं चिह्नं संस्थानं व्यञ्जनं रूपमित्यनर्थान्तरम्||९|| tr. none (Sanskrit mūla) · https://www.carakasamhitaonline.com/index.php?title=Jwara_Nidana THE CIRCULARITY, visible in one verse. The definiens is prādurbhūta-LAKṢAṆA, the manifested lakṣaṇa; the definiendum is liṅga; and the second half then declares lakṣaṇa a synonym of liṅga. If they were strictly synonymous the definition would say nothing. Retrieved and string-matched by me. ### Charaka Samhita Nidāna Sthāna 1 (Jvara Nidāna):8, checked against the source > पूर्वरूपं प्रागुत्पत्ति लक्षणं व्याधेः||८|| tr. none (Sanskrit mūla) · https://www.carakasamhitaonline.com/index.php?title=Jwara_Nidana The same word doing the same job one verse earlier: pūrvarūpa is the pre-manifestation lakṣaṇa of the disease. So in Ni. 1.8-9 lakṣaṇa is the GENUS of which pūrvarūpa and liṅga are the temporally-divided species, and is simultaneously listed as a synonym of one of the species. ### Charaka Samhita Nidāna Sthāna 1 (Jvara Nidāna):9, translator's footnote, checked against the source > 'Lakshana' is from the root 'laksha' to see or observe. Hence, that by which anything else is seen is called 'Lakshana.' tr. Avinash Chandra Kaviratna · https://archive.org/stream/BIUSante_47357/BIUSante_47357_djvu.txt Public-domain etymology. Retrieved and string-matched by me from the footnote in which Kaviratna glosses six of the seven synonyms separately, which is itself evidence that he did not regard them as interchangeable in use. ### Ashtanga Hridaya Nidāna Sthāna 1 (Sarvaroga Nidāna):5, address only, nothing quoted to check Lakṣaṇa appears as one of Vagbhata's six synonyms of rūpa (saṃsthāna, vyañjana, liṅga, lakṣaṇa, cihna, ākṛti). Devanagari mūla sighted on the retrieved page; not quoted per the rule for this text. ### Madhava Nidana 1 (Pañca Nidāna Lakṣaṇa):7, and the chapter title itself, address only, nothing quoted to check Two uses on one page. At 1.7 lakṣaṇa is a synonym of rūpa; in the chapter title Pañca Nidāna Lakṣaṇa it means the definition or characterisation of the five. The retrieved page prints both. ## Not to be confused with - **liṅga.** Declared anarthāntara at Ca. Ni. 1.9, yet liṅga is what one infers FROM (Kaviratna: root 'ligi', to go, hence to proceed to an inference) while lakṣaṇa is what one observes BY (root 'laksha', to see). Sign-as-evidence versus mark-as-criterion. - **rūpa.** The headword of the pentad's third member in Vagbhata and Madhavakara. Lakṣaṇa is a synonym of it there, but lakṣaṇa alone carries the definitional sense that rūpa does not. - **lakṣaṇa as 'definition' in śāstra.** THE DISTINCTION THIS RECORD IS FOR. Across Sanskrit systematic literature lakṣaṇa means the defining characteristic, the definiens, as in Madhava Nidana's own chapter title. Reading every occurrence as 'symptom' mistranslates chapter headings and definitional passages throughout the corpus. - **pūrvarūpa.** Not a contrast but a containment: Ca. Ni. 1.8 makes pūrvarūpa a KIND of lakṣaṇa (the pre-manifestation kind). A reader who treats lakṣaṇa as equal to liṅga will find Ni. 1.8 incoherent. - **cihna.** Kaviratna glosses cihna as 'literally a mark'. Closest to lakṣaṇa of the seven, and the pair is where an actual semantic distinction, if any survives, would have to be argued. ## Renderings that do not hold - symptom. The default rendering and wrong wherever the word is doing definitional work, which includes Ca. Ni. 1.8, the definiens of Ca. Ni. 1.9, and the title of Madhava Nidana chapter 1. It also imports the modern sign/symptom split, which the Sanskrit does not make. - sign. Better than 'symptom' but still one-sided: it renders the evidential half and drops the definitional half. - characteristic feature. WHO's gloss, and the best of the short ones, but by placing lakṣaṇa inside the ITA-4.5.5 'Signs and symptoms' block WHO commits it to the clinical sense and makes the definitional sense uncodeable. - lesion. Seen in older translations influenced by pathological anatomy. A lakṣaṇa need not be structural at all. ## Open questions Recorded rather than resolved. - Whether any classical commentator addresses the circularity of Ni. 1.8-9 directly, where lakṣaṇa is both the genus and a synonym of one species. Chakrapani is the place to look and I did not retrieve him. - Whether the definitional sense has ever been given a terminology code by anyone. WHO has not; I could not check NAMASTE (the terminologies path 302-redirects) and could not query ICD-11 TM2 (search endpoints returned 404). - Whether any Sanskrit lexicographic study treats the seven Ni. 1.9 synonyms as genuinely distinct. Kaviratna's footnote glosses six of them separately, which implies he thought so, but he does not argue it. - Modern literature: none found. I did not locate any peer-reviewed paper on the semantics of lakṣaṇa, and I did not run a dedicated PubMed query because the term is too ambiguous for a useful search. That is a gap in this record, honestly stated rather than filled. ## Citation Age Ayurveda Nighantu, "lakṣaṇa", https://nighantu.ageayurveda.com/lexicon/lakshana/, CC BY 4.0.
