iumentum

A back-formation from iumenta, from iungere (“to yoke, to join”) + -menta (“forming collective nouns”).

• (Classical) IPA^(key): /juːˈmen.tum/, [juːˈmɛn.tũ]

iūmentum n (genitive iūmentī); second declension

1. (zoology) A draft animal, a beast of burden, a large domestic animal suitable for drawing carts and carriages: a cow, horse, mule, or donkey.
   • 1st century, L. Iunius Moderatus Columella, De Res Rustica, Book VI, Preface, Sect. 3:

     Unde etiam iumenta et armenta nomina a re traxere quod nostrum laborem vel onera subvectando vel arando iuvarent.

     And so it is that iumenta and armenta draw their names from the fact that they aid our work either by bringing up burdens or by plowing.

2. (zoology) Synonym of iumenta: such animals taken collectively.
3. (vehicles) A vehicle drawn by such animals: a wagon, a carriage, a cart.

In Latin, iumenta are distinguished both from the armenta used to draw ploughs and from weaker domestic animals (pecora) unable to pull heavy loads such as riding horses and donkeys used only as pack animals.

Second declension.

• (vehicle): carrus, plaustrum

• (beast of burden): bos, equus, asinus, mulus
