Meaning and translation features
The Latin verb in the subjunctive mood in medical practice always carries a shade of obligation. The physician does not state a fact, but gives an order.
Such a form can be translated into Russian in two equivalent ways:
- By the infinitive form of the verb. This is the most frequent and natural option of command for the Russian language. For example, the Latin word is translated simply as "Mix!", "Designate!" or "Dispense!".
- Through a construction with the word "let". This option is more commonly used for the passive voice, when the action is directed at the drug itself. For example: "Let it be mixed", "Let it be dispensed" or "Let them be mixed" (if there are several components).
How the subjunctive stem is formed
To construct the subjunctive form, you need to take the dictionary form of the verb, isolate the usual stem from it, and modify it according to strict rules depending on the conjugation type. Personal endings will then be added only to this updated stem.
Stem transformation rules:
- For verbs of the 1st conjugation, the characteristic final vowel of the stem -a is dropped, and the vowel -e is put in its place.
- For verbs of the 2nd, 3rd, and 4th conjugations, the original stem vowel is retained (or consonant, as in the 3rd conjugation), but the suffix -a is additionally appended to it.
Let us look at the transformation using specific verbs:
| Conjugation | Verb | Usual stem | Conjunctivus stem |
|---|---|---|---|
| I (To designate) | signo, āre | signa- | signe- |
| II (To mix) | misceo, ēre | misce- | miscea- |
| III (To repeat) | repeto, ĕre | repet- | repeta- |
| IV (To finish) | finio, īre | fini- | finia- |
System of personal endings
Although verbs in classical Latin grammar change across three persons, within the narrow scope of medical prescriptions, only the 3rd person is required. The physician addresses the pharmacist in absentia, prescribing what should happen to the medication (let him make, let it be mixed).
Endings depend on number and voice:
- Active voice (Activum) indicates that someone must perform the action: singular — -t, plural — -nt.
- Passive voice (Passivum) indicates that the action must be performed on the object: singular — -tur, plural — -ntur.
Examples of conjugation in the active voice
The active voice (Activum) carries the meaning of "Let him make..." or a direct command using an infinitive ("To make!").
- 1st conjugation (stem signe-): signet (let him designate, designate!) — signent (let them designate, designate!).
- 2nd conjugation (stem miscea-): misceat (let him mix, mix!) — misceant (let them mix, mix!).
- 3rd conjugation (stem repeta-): repětat (let him repeat, repeat!) — repětant (let them repeat, repeat!).
- 4th conjugation (stem finia-): finiat (let him finish, finish!) — finiant (let them finish, finish!).
Examples of conjugation in the passive voice
The passive voice (Passivum) is translated as "Let it be done..." or with the same impersonal infinitive ("To be done!").
- 1st conjugation (stem signe-): signētur (let it be designated, designate!) — signentur (let them be designated, designate!).
- 2nd conjugation (stem miscea-): misceātur (let it be mixed, mix!) — misceantur (let them be mixed, mix!).
- 3rd conjugation (stem repeta-): repetātur (let it be repeated, repeat!) — repetantur (let them be repeated, repeat!).
- 4th conjugation (stem finia-): finiātur (let it be finished, finish!) — finiantur (let them be finished, finish!).
Briefly: answers to topical questions
How is the subjunctive form formed for the irregular verb fio (to result, to be formed)?
The subjunctive form for the irregular verb fio is formed by adding the suffix -a- to the stem fi-. This verb has only a passive meaning, but takes active voice endings.
In prescription formulations, third-person forms are used:
- Singular (fiat) — let it result.
- Plural (fiant) — let them result.
Usually, these forms are used in subordinate clauses of purpose after the verb Misce along with the name of the dosage form in the nominative case.
To avoid confusing stem modifications, remember: the 1st conjugation "loses A and finds E", while all other conjugations (2nd, 3rd, 4th) simply "together add A" to the end of their stem.
Class and exam questions
Why are there no 1st- and 2nd-person forms in the ending tables?
They are simply not used in medical prescribing. The doctor writes a prescription implying a 3rd-person action (let the pharmacist dispense, let the ointment be mixed), so learning other persons for writing prescriptions is not required.
How to distinguish active voice from passive voice by ending?
In the passive voice, an element with the letter "r" is always added to the stem. While in the active voice we simply see -t or -nt, in the passive they turn into -tur and -ntur respectively.
Can the subjunctive be translated with a future tense verb?
No, that is a mistake. The subjunctive in a prescription expresses a command, not a prediction of the future. It is correct to translate either with an infinitive ("Mix!") or an imperative construction ("Let it be mixed").
