Definition: Acinous, in ancient Greek, refers to the feeling of being cold or freezing. It has several meanings: 1.
The coldness of ice (in Greek) - it comes from "ainas" which means "ice", as well as the root word "aios" which means "to feel". 2.
The coldness of frost and snow - it comes from the word "ainsis", which also has roots in "aios". In ancient Greek, "ainsis" was a shortened form of "ainos", meaning "to be cold and hard". 3.
The coldness of snowflakes - it comes from the root "aison," which means "cold" or "not warm." In modern English, 'acinous' often refers to something that is cold in feel or that seems to be very cold. For example: 1. The winter weather was a cinous sensation, but we had no choice about where we lived. 2. I found the air quite icy and cold today. 3. The weather was quite a cinous and cold for the time of year. 4. He seemed like he'd been in very cold and dry conditions. 5. The house was as cold as ice, with the windows half open and the air coming in from outside. Note: As 'acinious' is also a part of the Latin root "ainus" (an icy or frosty) it could be used to refer to something that is cold but feels very icy like water.
