List of Latin phrases (A)

This page lists English translations of notable Latin phrases, such as veni vidi vici and et cetera. Some of the phrases are themselves translations of Greek phrases, as Greek rhetoric and literature reached its peak centuries before the rise of ancient Rome.

This list covers the letter A. See List of Latin phrases for the main list.

Latin	Translation	Notes
a bene placito	from one well pleased	i.e., "at will" or "at one's pleasure". This phrase, and its Italian (beneplacito) and Spanish (beneplácito) derivatives, are synonymous with the more common ad libitum (at pleasure).
a capite ad calcem	from head to heel	i.e., "from top to bottom", "all the way through", or "from head to toe". See also a pedibus usque ad caput.
a contrario	from the opposite	i.e., "on the contrary" or "au contraire". Thus, an argumentum a contrario ("argument from the contrary") is an argument or proof by contrast or direct opposite.
a Deucalione	from or since Deucalion	A long time ago; from Gaius Lucilius, Satires VI, 284
a falsis principiis proficisci	to set forth from false principles	Legal phrase. From Cicero, De Finibus IV.53.

a posse ad esse	from being able to being	"From possibility to actuality" or "from being possible to being actual".
a posteriori	from the latter	Based on observation, i. e., empirical evidence. Opposite of a priori. Used in mathematics and logic to denote something that is known after a proof has been carried out. In philosophy, used to denote something known from experience.
a priori	from the former	Presupposed independent of experience; the reverse of a posteriori. Used in mathematics and logic to denote something that is known or postulated before a proof has been carried out. In philosophy, used to denote something is supposed without empirical evidence. In everyday speech, it denotes something occurring or being known before the event.
a solis ortu usque ad occasum	from sunrise to sunset
ab absurdo	from the absurd	Said of an argument either for a conclusion that rests on the alleged absurdity of an opponent's argument (cf. appeal to ridicule) or that another assertion is false because it is absurd. The phrase is distinct from reductio ad absurdum, which is usually a valid logical argument.
ab abusu ad usum non valet consequentia	The inference of a use from its abuse is not valid	i.e., a right is still a right even if it is abused (e.g. practiced in a morally/ethically wrong way); cf. § abusus non tollit usum.
ab aeterno	from the eternal	Literally, "from the everlasting", "from eternity", or "from outside of time". Philosophically and theologically, it indicates something, e. g., the universe, that was created from outside of time. Sometimes used incorrectly to denote something, not from without time, but from a point within time, i.e. "from time immemorial", "since the beginning of time". or "from an infinitely remote time in the past")
ab antiquo	from the ancient	i.e., from ancient times
ab epistulis	from the letters	Regarding or pertaining to correspondence. Ab epistulis was originally the title of the secretarial office in the Roman Empire
ab extra	from beyond/without	Legal term denoting derivation from an external source, as opposed to a person's self or mind—the latter of which is denoted by ab intra.

ab inconvenienti	from an inconvenient thing	Neo-Latin for "based on unsuitability", "from inconvenience", or "from hardship". An argumentum ab inconvenienti is one based on the difficulties involved in pursuing a line of reasoning, and is thus a form of appeal to consequences. The phrase refers to the legal principle that an argument from inconvenience has great weight.
ab incunabulis	from the cradle	i.e., "from the beginning" or "from infancy". Incunabula is commonly used in English to refer to the earliest stage or origin of something, and especially to copies of books that predate the spread of the printing press c. AD 1500.
ab initio	from the beginning	i.e., "from the outset", referring to an inquiry or investigation. Ab initio mundi means "from the beginning of the world". In literature, it refers to a story told from the beginning rather than in medias res ('from the middle'). In science, it refers to the first principles. In other contexts, it often refers to beginner or training courses. In law, it refers to a thing being true from its beginning or from the instant of the act, rather than from when the court declared it so. Likewise, an annulment is a judicial declaration of the invalidity or nullity of a marriage ab initio: the so-called marriage was "no thing" (Latin: nullius, from which the word "nullity" derives) and never existed, except perhaps in name only.
ab intestato	from an intestate	i.e., from a (dead) decedent, who died without executing a legal will; cf. ex testamento
ab intra	from within	i.e., from the inside, as opposed to ab extra ("from without").
ab invito	against one's will
ab irato	from/by an angry person	More literally, "from/by an angry man". Though the form irato is masculine, the application of the phrase is not limited to men. Rather, "person" is meant because the phrase probably elides homo ("man/person"), not vir ("man"). It is used in law to describe a decision or action that is motivated by hatred or anger instead of reason and is detrimental to those whom it affects.
ab origine	from the source	i.e., from the origin, beginning, source, or commencement; or, "originally". Root of the word aboriginal.
ab ovo	from the egg	i.e., from the beginning or origin. Derived from the longer phrase in Horace's Satire 1.3: "ab ovo usque ad mala", meaning "from the egg to the apples", referring to how Ancient Roman meals would typically begin with an egg dish and end with fruit (cf. the English phrase soup to nuts). Thus, ab ovo means "from the beginning", and can connote thoroughness.

absente reo (abs. re.)	[with] the defendant being absent	Legal phrase denoting action "in the absence of the accused".

Also extended to absit invidia verbo ("may ill will/envy be absent from these words"). cf. absit iniuria verbis.
absit omen	absent from omen	i.e., "let this not be a bad omen", expressing the hope that something ill-boding does not turn out to be bad luck in the future.

It was used as a referential year in ancient Rome from which subsequent years were calculated, prior to being replaced by other dating conventions. Also anno urbis conditae (AUC), literally "in the year of the founded city".
