“Petty officer Adams, grapes needed on deck.” EOOW

“Grapes needed on deck, AYE” PO Adams in the oil shack.

That final spoken word was the most important, AYE, or yes I understand in Navy speak. No matter what else was spoken, if AYE were added it would have been understood by both parties that the order was understood and will be carried out.
People do not use, yes, yeah, ok, alright, sure, yup, or okey dokey in the Navy, they use AYE.

This is primarily to make sure the word is not misunderstood, and partly due to tradition. The word is said to have originated in Middle English in or around the 13th century. The whole Etymology of the word is Middle English, from Old Norse ei; akin to Old English ā always, Latin aevum age, lifetime, Greek aiōn age.

“Carry on shipmate!”

“AYE!!”
