Law and Necessity (Letter D)

In Latin, phrases starting with the letter D emphasize the immutability of rules and harsh living conditions. A classic example is the legal expression Dura lex, sed lex, which reminds us that the law is harsh, but it is the law. No matter how burdensome a regulation may seem, it must be followed without exception. A philosophically similar concept is reflected in the short phrase Dura necessĭtas, meaning grim necessity, when circumstances dictate the only possible course of action for a person.

Experience, Cognition, and Errors (Letter E)

The letter E begins an extensive layer of vocabulary describing human nature, education, and science. The famous saying Errāre humānum est perfectly conveys our attitude toward weaknesses — to err is human. However, in the scientific community, it is important to avoid at all costs Error fundamentalis — a fundamental fallacy capable of destroying the entire theory, because Ex nihilo nihil (nothing comes from nothing).

Education and the accumulation of knowledge require colossal efforts. The ancient Romans were certain that strict training is the best (Eruditio aspĕra optĭma est), and experience is the teacher of all things (Est rerum omnium magister usus). In all matters, it is important to remember Horace's precept: there is a measure in things (Est modus in rebus).

Specific turns of phrase are especially relevant for physicians and researchers:

  • Exĭtus letālis — fatal outcome, a crucial clinical term.
  • Ex tempŏre — preparation of a drug at the moment needed or as required.
  • Experimentum crucis — crucial experiment (literally "test by the cross"), confirming a hypothesis.
  • Ex promptu — acting extempore, without preliminary preparation.
  • Ex cathĕdra — speaking authoritatively, in an official setting (sometimes used ironically as "dogmatic").
  • Ex officio — acting ex officio or by virtue of one's office.

In everyday speech and literature, one also frequently encounters the abbreviation Etc. (et caetĕra — and so forth), the phrases Exempli causa (for example), Eo ipso (thereby), and Ex libris (from the books of such-and-such author). A sane approach to needs is described by the phrase: Edĭmus, ut vivāmus, non vivĭmus, ut edāmus (we eat to live, not live to eat), while true craftsmanship is seen in details — Ex ungue leōnem (from the claw one knows the lion).

Fate, Labor, and Medical Ethics (Letter F)

Aphorisms starting with F are full of calls to action and reflections on purpose. It is believed that every man is the artisan of his own fortune (Faber est suae quisque fortūnae), and fortune favors the brave (Fortes fortūna juvat), despite the fact that fortune is blind (Fortūna caeca est). In work, especially medical practice, it is important to adhere to the principle Festīna lente — make haste slowly, do not do things in a rush, for indeed the end crowns the work (Finis corōnat opus). A call to creation sounds in the phrase Fac et spera! (Work and hope!), and radical measures are described by the harsh expression Ferro ignīque (with fire and sword, by iron and fire).

The famous phrase Feci, quod potui, faciant meliōra potentes means: "I have done what I could, let those who can do better." This is an expression of humility before the complexity of a task. At the same time, one should remember trust: Fide, sed, cui fidas vide — trust, but look whom you trust.

In clinical practice, the term Facies Hippocratĭca stands out — Hippocratic facies, describing the specific, sharpened facial features of a dying patient. At the same time, ancient physicians subtly noted human psychology: all of us, as long as we are healthy, easily give good advice to the sick (Facĭle omnes, cum valēmus, recta consilia aegrōtis damus).

Also, in office work, the concept of Fac simĭle (facsimile) became established — an exact reproduction of someone's signature or handwriting (literally "make similar").

Persistence and Gratuitousness (Letter G)

The section on the letter G is small, but very concise. The word Gratis means free of charge or gratis, and the expression Gratis dictum describes a statement that is said for nothing, meaning it is unsubstantiated and unconvincing. Ovid's famous quote Gutta cavat lapidēm, non vi, sed saepe cadendo deserves special attention, teaching that a drop hollows out a stone not by force, but by falling frequently. This is a powerful metaphor emphasizing the exceptional importance of persistence, discipline, and regularity in any endeavor, whether studying Latin or treating a severe illness.
