"Bonus -a -um" is a regular 1st and 2nd declension adjective. This means: -
Masculine forms follow the 2nd declension (-us/-er type) -
Feminine forms follow the 1st declension (-a type) -
Neuter forms follow the 2nd declension neuter (-um type)
Singular: -
Masculine: bonus (nom.), bonī (gen.), bonō (dat.), bonum (acc.), bonō (abl.) -
Feminine: bona (nom.), bonae (gen.), bonae (dat.), bonam (acc.), bonā (abl.) -
Neuter: bonum (nom.), bonī (gen.), bonō (dat.), bonum (acc.), bonō (abl.)
Plural: -
Masculine: bonī (nom.), bonōrum (gen.), bonīs (dat.), bonōs (acc.), bonīs (abl.) -
Feminine: bonae (nom.), bonārum (gen.), bonīs (dat.), bonās (acc.), bonīs (abl.) -
Neuter: bona (nom.), bonōrum (gen.), bonīs (dat.), bona (acc.), bonīs (abl.)
-
Forgetting Agreement: The most common error is failing to make the adjective agree with its noun in gender, number, and case. Remember: a feminine noun requires a feminine adjective form, regardless of the biological gender of any person involved. -
Confusing Endings: Students often confuse: -
bonae (gen. sing. fem. or nom. pl. fem.) with bonī (gen. sing. masc./neut. or nom. pl. masc.) -
bonō (dat./abl. sing. masc./neut.) with bonā (abl. sing. fem.) -
Word Order Assumptions: Unlike English, Latin adjectives can appear before or after their nouns. Don't assume "bonus medicus" and "medicus bonus" have different meanings—both mean "good doctor."
English adjectives are invariable—"good" remains "good" regardless of what it modifies. Latin adjectives must change their endings: -
English: "good herb, good doctor, good remedy" -
Latin: "herba bona, medicus bonus, remedium bonum"
-
Identify the noun you want to modify -
Determine its gender (masculine, feminine, or neuter) -
Identify its number (singular or plural) -
Identify its case (nominative, genitive, dative, accusative, ablative) -
Select the matching form of "bonus -a -um" -
Place the adjective either before or after the noun (both positions are correct)
In medical Latin, "bonus" frequently appears in: -
Prescriptions: "aqua bona" (good/pure water) -
Botanical descriptions: "herba bona prō..." (herb good for...) -
Quality assessments: "medicāmentum bonum" (good medicine) -
Prognoses: "sīgnum bonum" (good sign)

In ancient Roman medicine, the concept of "bonus" extended beyond mere effectiveness. A "bonus medicus" was not only skilled but also ethical, following the Hippocratic tradition. Similarly, "bonae herbae" were not just effective plants but those harvested at the proper time, prepared correctly, and stored appropriately.
Medieval herbalists believed that "bonae herbae" often revealed their medicinal properties through their appearance—a concept known as the Doctrine of Signatures. Plants considered "good" for certain ailments often resembled the body part they were meant to heal.
The term "bonus" in pharmaceutical contexts implied: -
Purity of ingredients -
Proper preparation methods -
Appropriate storage conditions -
Proven effectiveness
Historical pharmacopoeias frequently used "bonus" to distinguish superior grades of medicines from inferior ones. For example, "thēriaca bona" indicated a properly prepared theriac with all genuine ingredients, as opposed to cheaper substitutes.
Today's pharmaceutical standards echo these ancient concerns for "good" medicine: -
Good Manufacturing Practices (GMP) reflect the "bonus" tradition -
The phrase "bona fide" (in good faith) derives from this usage -
Quality control in herbal medicine continues to distinguish "good" from inferior products
Monastery gardens traditionally divided plants into categories, with "herbae bonae" occupying prime positions. These "good herbs" were those proven effective through centuries of use, easy to cultivate, and versatile in their applications.

From Pliny the Elder's Naturalis Historia (Book XX, Chapter 73)
Part F-A (Interleaved Text)
Rūta rue et also ipsa itself inter among medicamenta medicines bonae of good nōtae reputation est is. Seritur It is sown et both sēmine from seed et and surculō from cutting. Melius Better autem however surculō by cutting, quia because difficilius with more difficulty sēmine from seed prōvenit it grows. Bonae Good frondis foliage colōrem color habet it has quae which maximē especially viret is green. Ūtilis Useful est it is contrā against venēna poisons omnium of all serpentium serpents.
Rūta et ipsa inter medicamenta bonae nōtae est. Seritur et sēmine et surculō. Melius autem surculō, quia difficilius sēmine prōvenit. Bonae frondis colōrem habet quae maximē viret. Ūtilis est contrā venēna omnium serpentium.
Rue itself is also among medicines of good reputation. It is sown both from seed and from cutting. Better, however, by cutting, because it grows with more difficulty from seed. It has the color of good foliage which is especially green. It is useful against the poisons of all serpents.
Pliny uses "bonus" twice in this passage, demonstrating two different but related meanings. First, "bonae nōtae" (of good reputation) indicates rue's established medicinal value—it's not just effective but well-regarded by practitioners. Second, "bonae frondis" (of good foliage) describes the physical characteristics that indicate a healthy, medicinally potent plant. This dual usage reflects the Roman understanding that a medicine's reputation and its physical qualities were interconnected.
-
"bonae nōtae": genitive singular feminine, describing quality or characteristic ("of good reputation") -
"bonae frondis": genitive singular feminine, showing possession or description ("of good foliage") -
Both uses demonstrate how "bonus" in the genitive can indicate quality or characteristic -
Note the comparative "melius" (better), showing the related adverb form -
The passage demonstrates typical Latin word order with verbs often coming at clause ends
