"Succision" Natural Recordings by Native Speakers
Succision is not a word in the English language. However, it may be a misspelling of the word "suction", which refers to the act of drawing in or holding onto something using a vacuum or suction force.
Alternatively, it could be related to "succession" (note the double "c"), which refers to the act or process of succeeding to a position, power, or authority.
