24.08.26: alibi ... and an addendum

It’s a straightforward question since the word crops up in countless detective movies:

  • alibī: elsewhere; in law, it refers to the defence plea that the accused was elsewhere at the time of the crime  
  • aliās: the English term ‘alias’ refers to a person who goes by alternative names. The original Latin adverb means ‘at another time; on another occasion’.
  • alumnus, -ī [2/m]: pupil (male);  alumna, -ae [1/f]: pupil (female)

The fourth option (addendum) features a useful point of Latin grammar.

addendum: this is an example of a Latin future passive participle, also known as a gerundive:

The gerundive most often refers to something that needs to be or has to be done. It is formed from the stem of the present tense with a distinctive -nd- ending + the adjective endings -us, -a, -um; below are its forms with its basic meaning

laudō, laudā¦re [1]: praise > lauda- > laudandus, -a, -um: (which) is / needs / has to be praised 

timeō, timē¦re [2]: fear > time- > timendus, -a, -um│ which is to be feared

dēleō, dēlē¦re [2]: destroy > dēle- > dēlendus, -a, -um│ which is to be destroyed

Carthāgō dēlenda est (Cato the Elder) | Carthage is to be / has to be / must be destroyed.

dūcō, dūce¦re [3]:lead > dūc- > dūcendus, -a, -um│ which is to be led

3-iō and 4th conjugation have -ie- as the stem before the ending is added

capiō, cape¦re [3-iō] > capie¦ndus, -a, -um│ which is to be captured

audiō, audī¦re [4] > audie¦ndus, -a, -um│ which is to be heard

English has derived nouns from this construction:

(1) addō, addere [3]: add > addendus, -a, -um | which is to be added

> Engl. deriv: addendum – something that needs to be added)

When the boss forgot to include something in a document, he may send you an addendum (or several addenda).

(2) corrigō, corrigere [3]: correct > corrigendus, -a, -um | which is to be corrected

> Engl. deriv: corrigendum – something that needs to be corrected)

Less so nowadays, but a book may contain a corrigendum or, more commonly, a list of corrigenda i.e. this is added to the book / document after its publication to refer to errors that have been noted and, presumably, are to be corrected in the next edition or which need to be corrected by the reader when they appear. 

(3) Business meetings may begin with an agenda, a summary of items that need to be done during the meeting.

agō, agere [3]: do > agendus, -a, -um | which is to be done

(4) You may receive a memo by email i.e. a memorandum – something that needs to be remembered – or maybe you have several things you need to remember: memoranda

memorō, memorāre [1]: remind; bring to mind > memorandus, -a, -um | which is to be brought to mind

(5) two proper nouns in English are derived from the gerundive forms:

amō, amāre [1]: love > amandus, -a, -um | which (who) is to be loved > Amanda

mīror, mīrārī [1/deponent]: wonder at > mīrandus, -a, -um | which (who) is to be wondered / admired at

The formidable boss of Runway in “The Devil Wears Prada” is Miranda Priestly, she who is to be wondered / marvelled at – the perfect choice of name for her character.
