Impetuous, impetus and centripetal...

Impetuous (adj): violent, hasty, rash.

Well although these words are common in vernacular, there is a lot hidden behind them. All these words come from the Latin root “petere” which means “to seek, attack, demand, make for”. This word is derived from the word impetus itself which can be split up as “in” which means “against” + “petere” which means, “to seek” Thus something that is seeking something, or moving towards some other thing will have a some amount of energy associated with it. This is called as the impetus, or in simple words “force”.

Contextual example
All his impetuous decisions about his career had turned out disastrously.

Impetus (N): moving force, incentive, stimulus.

Contextual example:
The invention of wheel provided an impetus, to the development of human race by facilitating the rapid movement of goods from one place to another.

Centripetal (Adj): Tending towards center.
This word can be hacked up as “centrum” which means, “Center” + “”petere” which means, “to seek”. Thus centripetal force is the force that is acting towards the center. While the centrifugal force acts away from the center (centrum + fugere) (Sit back and relax because pretty soon I would be posting the words related to this root: fugere).

Contextual example:
As the turbine (comes from “turbare” which means confusion) blades were going to be run at very high rotational velocities the design was based on maximum centripetal and centrifugal forces that could be generated at those speeds.

One very commonly used cognate of this root is, any guesses? Or should I “repeat” my question. Well the word is “repeat”.

Repeat:
To state something, to do something again

“re” which means “again” + “petere”.

I must say that the cognate seems not at all obvious but now that you know it, you can utilize it as an anchor word.

Whew! that was a lot especially after being in the office for the whole day and then writing the post from 3:00 to 3:32 AM.
