Definition of impetus in English:
- The requirements of homogeneous diesel combustion processes give additional impetuses to the continued development of piezo controls for unit injector systems.
- The expanded literature search was very coincident with the initial search, providing most of the same reasons, purposes, and impetuses for developing peer institution selection systems.
- One of the most interesting points to emerge is a recognition that with hindsight, European radicalism has once again written itself as a form of diffusionism, its sources and impetuses exclusive unto itself.
mid 17th century: from Latin, 'assault, force', from impetere 'assail', from in- 'towards' + petere 'seek'.
compete from (early 17th century):
This word is from Latin competere in its late sense ‘strive or contend for (something)’: the elements here are com- ‘together’ and petere ‘aim at, seek’. As well as giving us competition (early 17th century) this is also the source of competent (Late Middle English); while petere gives us: impetus [M17] and impetuous (Late Middle English) ‘seek towards, assail’; petition (Middle English) an act of seeking for something; petulant (late 16th century) originally immodest in what you seek; and repeat (Late Middle English) seek again.
