Where does the -ive suffix come from in 'restive'?

I saw a headline today about the volcano near Manila in the Philippines.

Restive Philippine volcano prompts evacuation

MSN News 12th January 2020

I was not familiar with the word 'restive' and thought it meant 'dormant', but it means the opposite :

  1. Characterized by erratic or adverse behaviour arising from discontent, disquiet, etc.

Oxford English Dictionary - requires subscription or library card

1: stubbornly resisting control : BALKY

2: marked by impatience or uneasiness : FIDGETY

Merriam Webster

So, it has the meaning 'restless'.

Where is the -ive suffix from ? I cannot think of another similar word. How does that suffix give the word the same meaning as 'restless' ?


It is actually a peculiar sense of restive as explained below:

restive (adj.):

early 15c., restyffe "not moving forward," from Middle French restif "motionless, brought to a standstill" (Modern French rétif), from rester "to remain" (see rest (n.2)). Sense of "unmanageable" (1680s) evolved via notion of a horse refusing to go forward.
