Use "windlessness" in a sentence
"Likewise, also, in the case of objects widely divergent, the examination of likeness is useful for purposes of definition, e.g. the sameness of a calm at sea, and windlessness in the air (each being a form of rest), and of a point on a line and the unit in number-each being a starting point."
"Heat lightning sometimes nickered yonder, and thunder muttered into windlessness."
"RAIN FELL slowly through windlessness, almost a mist."
