rūpa: what the term means and how it is translated
rūpa रूप is an Ayurvedic technical term. It is rendered into English in 8 different ways, which is the reason this page exists: the renderings do not agree, and the difference between them changes what the term is taken to mean.

How it is translated, and whether the translation holds
Each rendering is given with the source that uses it. The assessment is ours.
Signs and symptoms
WHO international standard terminologies on Ayurveda (2022) · ITA-4.5.5 (head term for the synonym set liṅgaḥ/liṅga, ākṛtiḥ, lakṣaṇam, cihnam, samsthānam, vyañjanam, rūpam) · standards body
WHO codes all seven synonyms under one ID, mirroring Ca. Ni. 1.9. The main description: 'Any morbid phenomenon or departure from the normal in structure, function or sensation, as experienced by the patient or observed by the physician and indicating a disease.'

Clinical presentation
WHO international standard terminologies on Ayurveda (2022) · ITA-4.5.5, last gloss in the synonym list (position-aligned to rūpam) · standards body
WHO gives six short glosses after the main description, against seven Sanskrit terms. Read positionally the main description carries liṅga and the six glosses run ākṛtiḥ 'Morphological sign', lakṣaṇam 'Characteristic feature', cihnam 'Sign or mark', samsthānam 'Resemblance', vyañjanam 'Figurative sign', rūpam 'Clinical presentation'. The alignment is inferred from the table layout, not labelled, and should be checked against the print edition.

those symptoms which manifest themselves on the appearance of the disease
Charaka Samhita, tr. Avinash Chandra Kaviratna (public domain) · Nidana Sthanam, Lesson I (rendering liṅga, not rūpa) · public-domain translation
Kaviratna translates the headword as 'Linga' because Charaka's verse does. Rūpa appears in his text only as one of the seven synonyms.
Rupa is form
Charaka Samhita, tr. Avinash Chandra Kaviratna (public domain), translator's footnote · Nidana Sthanam, Lesson I, footnote glossing the seven synonyms · public-domain translation
Kaviratna's entire gloss on rūpa, verbatim: "'Rupa' is form, — T,". Three words. Recorded because it is the only public-domain English etymology of the word in this sense and because its brevity is itself informative about how little the translator thought needed saying.
The full manifestation of a disease
Sushruta Samhita, tr. Kaviraj Kunja Lal Bhishagratna (public domain) · Sutrasthana, Chap. xxi · public-domain translation
Bhishagratna's phrase for the vyakti stage, where full manifestation is the fifth kriyākāla rather than a member of a pentad.

Charaka SamhitaNidāna Sthāna 1 (Jvara Nidāna):9 · checked against the source
प्रादुर्भूतलक्षणं पुनर्लिङ्गम्| तत्र लिङ्गमाकृतिर्लक्षणं चिह्नं संस्थानं व्यञ्जनं रूपमित्यनर्थान्तरम्||९||
Two separate claims in one verse. First, the definition, and its headword is LIṄGA, not rūpa: the manifested lakṣaṇa is liṅga. Second, seven words are anarthāntara: liṅga, ākṛti, lakṣaṇa, cihna, saṃsthāna, vyañjana, rūpa. So in Charaka rūpa is a synonym of the defined term, not the defined term. Retrieved and string-matched by me.
Charaka SamhitaNidāna Sthāna 1 (Jvara Nidāna):9 (unnumbered in Kaviratna at this point) · checked against the source
By 'Linga' is meant those symptoms which manifest themselves on the appearance of the disease. In this connection it should be stated that 'Linga', 'akriti', 'lak-shana', 'chihna', 'samsthana', 'vyanjana', and 'rupa', are words of the same import.
Public-domain English for both halves. 'lak-shana' carries a line-break hyphen from the scan, preserved verbatim.
Charaka SamhitaNidāna Sthāna 1 (Jvara Nidāna):9, translator's footnote · checked against the source
'Linga' comes from the root 'Ligi' to go. Hence, anything by which one can go to or proceed to an inference is called 'Linga.' It is a sign or symptom by which disease is to be inferred.
Public-domain etymology making the inferential structure explicit: a liṅga is what one reasons FROM. This is the semantic content that 'sign' preserves and 'symptom' loses.
Sushruta SamhitaSūtrasthāna 21 (running head 'Chap, xxi.] SUTRASTHANAM'):not numbered in Bhishagratna's edition · checked against the source
The full manifestation of a disease, such as a swelling, tumour, aneurism (Granthi), Vidradhi (abscess) and erysipelas (Visarpa) etc., fever or dysentery, signifies the complete development of the characteristic symp- toms, which should be regarded as the fifth occasion for medical treatment.
Sushruta's vyakti: full manifestation as the fifth kriyākāla. Again a stage, not an evidence type. 'symp-toms' carries a line-break hyphen, preserved verbatim.
Ashtanga HridayaNidāna Sthāna 1 (Sarvaroga Nidāna):5 · address only, nothing quoted to check
Vagbhata reverses Charaka's headword: the premonitory signs, on attaining clear manifestation (vyaktatā), are called RŪPA, and saṃsthāna, vyañjana, liṅga, lakṣaṇa, cihna and ākṛti are its synonyms. This is why the modern member of the pentad is called rūpa rather than liṅga. Devanagari mūla and verse number sighted on the retrieved page; not quoted per the rule for this text.
Madhava Nidana1 (Pañca Nidāna Lakṣaṇa):7 · address only, nothing quoted to check
Madhavakara follows Vagbhata's headword and gives five synonyms (vyañjana, liṅga, lakṣaṇa, cihna, ākṛti), omitting saṃsthāna. The three texts therefore give three different synonym lists for one concept.
Not to be confused with
- liṅga
- Charaka's headword for this concept, with rūpa as one of its synonyms; Vagbhata's synonym, with rūpa as the headword. The modern pentad follows Vagbhata. A citation of 'rūpa, Ca. Ni. 1.9' is therefore slightly wrong: the verse defines liṅga.
- pūrvarūpa
- Divided from rūpa by manifestation (prādurbhūta versus prāg-utpatti), and by Vagbhata's additional criteria of clarity and dosha-assignability. Vagbhata's Ni. 1.5 makes them continuous: the same signs, on becoming clear, are rūpa.
- lakṣaṇa
- Listed as a synonym in all three texts and coded under the same WHO ID, but Charaka uses lakṣaṇa in the DEFINIENS of both pūrvarūpa (Ni. 1.8) and liṅga (Ni. 1.9), which a true synonym could not do without circularity. See the lakṣaṇa record.
- vyakti
- The kriyākāla stage of manifestation (WHO ITA-4.6.x). Vyakti is when the signs appear; rūpa is what appears. Bhishagratna's Sūtra 21 passage is about the stage.
- rūpa in Sāṃkhya and Nyāya
- Form, or the object of the visual sense. A reader coming from philosophy will import that sense; Kaviratna's three-word footnote 'Rupa is form' is the bridge between the two and is easy to over-read.
- upadrava
- Complications arising during the course of a disease. Distinguished from rūpa by dependence on the primary disease, and by arising later. Not covered in this record; it belongs in its own.
Renderings that do not hold
- symptoms. Halves the concept. Modern usage reserves 'symptom' for what the patient reports and 'sign' for what the examiner finds; WHO's ITA-4.5.5 description spans both explicitly ('as experienced by the patient or observed by the physician'). Kaviratna's liṅga etymology ('by which one can go to an inference') is closer to 'sign'.
- form. The general Sanskrit sense of rūpa, and wrong here. In Ni. 1.9 the word is a technical synonym of liṅga.
- clinical picture. Suggests the whole presentation as a gestalt. Rūpa in the pentad is enumerable, texts list the rūpa of a disease as discrete items.
- pathognomonic sign. Over-specifies. Nothing in the definition requires a rūpa to be specific to one disease; upaśaya exists precisely because it often is not.
Open questions
Recorded rather than resolved. Each one is something this entry cannot currently settle.
- Whether WHO's six glosses at ITA-4.5.5 are intended to map one-to-one onto the seven Sanskrit terms in order. My mapping is read off the PDF table and could be wrong. This should be checked against the printed edition before the mapping is published.
- Whether any classical source distinguishes the seven synonyms in use, as Kaviratna does for the nidāna synonyms. He gives brief etymologies for six of them in the footnote to Ni. 1.9 but does not say they differ in application.
- Modern literature: EMPTY, and I did not find any. There is no peer-reviewed work I located on the reliability of Ayurvedic sign elicitation as such. The nearest reliability data I retrieved concerned prakriti assessment (e.g. PMID 33750638, ICC 0.72 vata / 0.58 pitta / 0.44 kapha for AyuSoft versus clinicians), which is a different object and is not recorded here as evidence about rūpa.
