"Decumanus" Natural Recordings by Native Speakers
A decumanus was a main street or a principal east-west road in ancient Roman cities and towns. It was a significant part of the city's planning and layout, often running perpendicular to the cardo, a major north-south road. The decumanus was often lined with important public buildings, shops, and residential properties, and was often the central axis of the city's plan.
Dectuplets are a set of 10 babies born to a single mother at the same time. The term "dectuplets" is a combination of "dec-" (meaning ten) and "twins", similar to octuplets (eight babies) and septuplets (seven babies). The term is often used to describe a rare and exceptional event in reproduction.
Decubation is not a commonly used word in English. After researching, I found that it is a rare or obsolete word that refers to the act of lying down or reclining in a horizontal position. It can also mean a position or attitude of lying down, especially when used in a medical or anatomical context. For example, in anatomy, decubation can refer to the relative position or posture of the body when a person is lying down.
