I want a word that means exactly "The action of ensuring something."

Example sentences (with the coined word ensurance):

"The neophyte may claim competence at the task, but your ensurance of its completion would ease my mind."

"...tasked with ensurance of a clear path through the debris."

"His duties consisted primarily of ensurance rather than active personal labor."

"Ensurance" itself does not appear in the dictionary; is there another word which means exactly this that I could substitute?

("Supervision" comes close but does not always connote a promised outcome for which the supervisor is directly accountable. It's the best substitute I can think of, personally, but fails to imply an actual guarantee.)

  • Why do you have to use the noun in the first place? Your question reads more like a request for proof-reading.

  • Did you look at the word assurance?

    ensurance appears in the OED as obsolete, with quotations from the 1600s only, although is appears in Johnson's Dictionary of 1755. M-W also lists it as obsolete.

The action of ensuring something is simply ensuring, so "..your ensuring its completion would ease my mind," and "...tasked with ensuring a clear path...," and "...his duties consisted primarily of ensuring that things were accomplished rather than active personal labor" all work well this way.

  • I assure you, he is ensuring your insurance.

According to Merriam-Webster, "ensurance" is a word, and I quite agree.

MERRIAM WEBSTER: the act of means of ensuring.
