Ambient is the word up for discussion today.
One of the main uses of this word that I have heard is ambient temperature. But, it seems there are other meanings too.
The context in which I heard it used means “of the surrounding area or environment.” Another definition is “existing on all sides.” This could relate to temperature. Also, if you have a tape recorder on a table, it will pick up ambient sounds. There can also be ambient light in a room too.
Ambient, in a general way can mean surrounding or encompassing.
A lesser known definition is “pertaining to sounds that create a peaceful/relaxed atmosphere.” I think “white noise” may fall in this category
Lastly, there is a definition that I never heard of. It states that the word ambient can mean “pertaining to close and constant social contact/communications.”
The derivation of the word is Latin: ambient-, ambiens, present participle of ambire to go around, from ambi- + ire to go.
