← Latin for Medics, Pharmacists and Herbalists
The Latin word pars, partis (feminine, 3rd declension) means "part, portion, share, or side." In medical and pharmaceutical contexts, this word is fundamental for describing anatomical divisions, dosage portions, recipe components, and regional classifications of the body or medicinal preparations.
Pars is a feminine noun of the third declension that denotes a portion or section of a whole. In medical Latin, it frequently appears in anatomical terminology (e.g., pars cephalica - the head portion), pharmaceutical recipes (e.g., partes aequales - equal parts), and botanical descriptions (e.g., pars herbae - part of the herb).
Q: What does "pars" mean in Latin? A: Pars means "part, portion, share, or side" in Latin. It is a feminine noun of the third declension, with the genitive form "partis."

Pars is a feminine noun of the third declension. This means it follows a specific pattern of endings that differs from first and second declension nouns that English speakers often learn first.
Singular: -
Nominative: pars (subject) - the part -
Genitive: partis (possession) - of the part -
Dative: partī (indirect object) - to/for the part -
Accusative: partem (direct object) - the part -
Ablative: parte (by/with/from) - by/with/from the part
Plural: -
Nominative: partēs - the parts -
Genitive: partium - of the parts -
Dative: partibus - to/for the parts -
Accusative: partēs - the parts -
Ablative: partibus - by/with/from the parts
-
Gender confusion: Students often assume pars is masculine because many body-part nouns are masculine. Remember: pars is always feminine. -
Genitive plural error: The genitive plural is partium, not *partum. This -ium ending is characteristic of i-stem third declension nouns. -
Ablative singular confusion: The ablative singular is parte, not *partī (which is dative). Many students confuse these two forms. -
Agreement errors: Adjectives must agree with pars in gender (feminine), number, and case. For example: "māior pars" not *māius pars.
Unlike English, where "part" remains unchanged regardless of its function in the sentence, Latin pars changes its ending to show its grammatical role. English relies on word order and prepositions; Latin uses case endings.
English: "of the part" / "to the part" / "with the part" Latin: partis (genitive) / partī (dative) / parte (ablative)
-
Identify the function: Determine whether pars is the subject, object, or has another role in your sentence. -
Choose the correct case: -
Subject = Nominative (pars/partēs) -
Direct object = Accusative (partem/partēs) -
Possession = Genitive (partis/partium) -
Indirect object = Dative (partī/partibus) -
Instrument/location = Ablative (parte/partibus) -
Check agreement: Ensure any adjectives match pars in gender (F), number, and case. -
Common phrases: -
partes aequālēs = equal parts -
prō parte = in part, partly -
ex parte = from the side of, partially -
māgnā ex parte = to a great extent
In medical Latin, pars frequently appears in: -
Anatomical terminology: pars thorācica (thoracic part) -
Prescriptions: Recipe format using partēs -
Proportions: Expressing ratios in remedies -
Regional descriptions: Different parts of organs or body regions

The concept of "parts" has been fundamental to medicine since antiquity. Roman physicians and pharmacists used pars in several important contexts that continue to influence modern medical terminology.
In ancient Roman pharmacies, medicines were often prepared using a system of parts rather than specific weights. This allowed for scalable recipes that could be adjusted based on available quantities. The phrase "partes aequālēs" (equal parts) appears frequently in historical pharmaceutical texts and remains abbreviated as "p.ae." or "aa" (ana) in modern prescriptions.
Roman anatomists, following Greek traditions, divided the body and its organs into parts for systematic study. This practice established many terms still used today: -
pars cephalica (head portion) -
pars cervīcālis (neck portion) -
pars thorācica (chest portion)
Herbalists have long recognized that different parts of plants possess different medicinal properties. Roman texts carefully specify which pars of a plant to use: -
pars aērea (aerial parts) -
pars subterrānea (underground parts) -
pars flōrida (flowering parts)
Medieval medical theory, building on classical foundations, often divided substances and body systems into four parts, corresponding to the four humors and elements. This quaternary division influenced how medicines were compounded and administered.
Understanding the historical use of pars helps modern practitioners: -
Read historical medical texts and manuscripts -
Understand the etymology of current medical terms -
Appreciate the continuity of pharmaceutical traditions -
Recognize Latin abbreviations still used in prescriptions
The precision required in specifying which pars of a plant or which pars of the body reflects the Roman attention to detail that characterized their approach to medicine and continues to influence medical practice today.

From Celsus, De Medicina 8.10.7, on surgical treatment of skull fractures:
Sī if vērō however pars part aliqua some ossium of bones īnfrācta broken inward est is et and aut either premit presses cerebrum brain aut or pungit pierces, eximenda to be removed est. it is. Idque and this commodissimē most conveniently fit is done modiolo with trepan quem which Graecī Greeks trypanon trypanon vocant. call. Is it concavus hollow teres round est is circāque and around īmum lowest part orbem circle serrātus serrated.
Sī vērō pars aliqua ossium īnfrācta est et aut premit cerebrum aut pungit, eximenda est. Idque commodissimē fit modiolo quem Graecī trypanon vocant. Is concavus teres est circāque īmum orbem serrātus.
If, however, some part of the bones is broken inward and either presses on the brain or pierces it, it must be removed. And this is most conveniently done with a trepan, which the Greeks call trypanon. It is hollow and round, and serrated around its lowest circle.
Celsus demonstrates the medical use of pars in a surgical context. The phrase "pars aliqua ossium" (some part of the bones) shows how Roman medical writers used pars to describe portions of anatomical structures requiring intervention. The precision of the language reflects the careful attention Roman surgeons paid to identifying exactly which part needed treatment.
-
pars aliqua: Nominative singular with indefinite adjective, serving as the subject -
ossium: Genitive plural of os, ossis (bone), showing possession -
īnfrācta est: Perfect passive, indicating completed action with ongoing relevance -
eximenda est: Gerundive construction expressing necessity -
The conditional sī clause introduces a medical scenario requiring specific intervention -
Note how pars functions as the critical subject identifying what portion requires surgical attention
This passage exemplifies the classical medical prescription format found in late medieval/early modern Latin pharmaceutical texts. The interleaved translation pattern (Latin term + English gloss) was standard in bilingual medical manuscripts.
---
- "Recipe take" — imperative command beginning prescription - Proportional measurements — duās...partēs (two parts), trēs partēs (three parts), quattuor partibus (four parts) - Botanical materia medica — chamomile, mint as base herbs
- Infusion technique — "cum aquae ferventis īnfunde" (pour boiling water over) - Temporal marker — "post hōrae" (after one hour) - Straining — "colā per linteum" (strain through linen) - Storage protocol — "vāse opercūlātō" (covered vessel)
- Frequency — "māne et vesperī" (morning and evening) - Conditional adjustment — dose escalation if pain persists - Quality control — pharmacist's role in mixing - Sweetening agent — honey for palatability - Safety caveat — warning against exceeding prescribed amounts
- Aerial parts doctrine — preference for above-ground plant material (flowers, leaves) over roots

This represents herbal decoction therapy typical of Galenic humoral medicine, where chamomile and mint addressed hot/cold imbalances and digestive disturbance.
This passage appears to be from a medieval or Renaissance herbal/pharmaceutical manual, describing preparation instructions. Here's a structured reading:
65.28 "The smallest parts suffice for obtaining the effect" - Minima...pars = smallest/least amount - sufficit = is sufficient - ad effectum obtinendum = for obtaining the effect/result
65.29 "The herbalist orders each part to be dried separately" - Herbārius = herbalist/apothecary - quamque partem = each part - sēpārātim = separately - siccārī iubet = orders to be dried
65.30 "Let all parts, well ground, make a homogeneous powder" - Omnēs partes = all parts - bene contūsae = well ground/crushed - homogeneum pulverem = homogeneous powder - faciant = let them make (subjunctive)
This describes a pharmaceutical preparation process: 1. Small quantities suffice for effectiveness 2. Individual ingredients must be dried separately 3. All dried ingredients should be thoroughly ground together into uniform powder
The decorative elements (✾ ❦) suggest this is from an ornately formatted manuscript or printed edition.
65.16 Recipe duās partēs flōrum chamomillae siccātōrum. Take two parts of dried chamomile flowers.
65.17 Addantur trēs partēs foliōrum menthae recentium. Let three parts of fresh mint leaves be added.
65.18 Cum quattuor partibus aquae ferventis īnfunde. Pour over with four parts of boiling water.

65.22 Māne et vesperī aequās partēs sūmat aeger. Let the patient take equal parts in the morning and evening.
65.23 Sī dolor persistit, tertia pars dōsis addī potest. If pain persists, a third part of the dose can be added.
65.24 Pharmacopōla omnes partēs secundum artem misceat. Let the pharmacist mix all parts according to the art.
65.25 Ūna pars mellis prō dulcōre additur. One part of honey is added for sweetness.
65.26 Cave nē māior pars quam praescrīpta sūmātur. Beware lest a greater part than prescribed be taken.
65.27 Ex herbae parte aēreā optimum remedium parātur. From the aerial part of the herb the best remedy is prepared.

Medical recipes in Latin follow specific grammatical conventions that differ from ordinary prose:
Recipe (take) traditionally opens prescriptions. This is the imperative singular, directly commanding action. Modern prescriptions still use "Rx" as an abbreviation of Recipe.
Medical Latin frequently uses the subjunctive mood for instructions: -
addantur (let them be added) - 3rd person plural passive subjunctive -
dentur (let them be given) - 3rd person plural passive subjunctive -
servētur (let it be kept) - 3rd person singular passive subjunctive -
misceat (let him mix) - 3rd person singular active subjunctive
The prescription format uses pars with numbers to indicate proportions: -
duās partēs (two parts) - accusative plural with numeral -
trēs partēs (three parts) - accusative plural -
ūna pars (one part) - nominative singular
Note: The number agrees with partēs in gender (feminine), number, and case.
-
partes aequālēs (p.ae. or aa) = equal parts -
quantum sufficit (q.s.) = as much as suffices -
prō dōsī = for a dose -
secundum artem (s.a.) = according to the art
Prescriptions specify when medicine should be taken: -
māne = in the morning -
vesperī = in the evening -
post hōrae partem = after a part of an hour
Medical warnings use specific patterns: -
cave nē + subjunctive = beware lest -
nē māior pars sūmātur = lest a greater part be taken
Medical Latin favors passive voice for objectivity: -
additur (is added) rather than "addit" (he adds) -
parātur (is prepared) rather than "parat" (he prepares)
The gerundive expresses purpose or necessity: -
ad effectum obtinendum = for obtaining the effect -
siccārī = to be dried
