The suffix -sion means the state or quality (of an object). This suffix appears in loanwords (words adopted from other languages with little or no modification) from Latin, and transforms a word into a verb.
Organic weed control encourages weed suppression rather than elimination.
How the Word Came to Be
The word suppression means the act of keeping something from happening. The base word, suppress means to put an end to, and the suffix -sion means the state. The combination of the word and the suffix means the state of putting and end to, which would be keeping something from happening.
