Borrowed from the Latin - jentaculum (pertaining to breakfast, particularly taken after getting up) + English suffix ar (of. near, or pertaining to) forming adjectives.  

The first thing I thought of when I saw this word was Denny's, I.H.O.P., and Waffle House (just picking places that the most people might know).  

The jentacular aromas in my kitchen are different as I'm allergic to eggs.

Denny's = pie and coffee all night long

I.H.O.P. = pancakes and surly waitresses

Waffle House = clouds of cigarette smoke and ashes in your eggs

The 1st century Latin poet Martial says that ientaculum occurred between 3:00 and 4:00 in the morning. While the 16th century French classical scholar Claudius Salmasius (Claude Saumaise) says it occurred between 9:00 and 10:00. Frankly, I'm putting my money on the poet from Ancient Rome who enjoyed his bread, cheese, olives, salad, nuts, raisins, and cold meat topped off with a mixture of wine, honey, and aromatic spices in the wee hours of the morning over some French dude who went around using his pen name. I've known some Claudes in my life from a great-uncle who used his middle name, an Air Force pilot who pronounced it like those puffy things floating in the sky, and a guy from South Dakota who pronounced it as if it rhymed with "dud".

I was only thinking of the smells of food when you walk into those places.

You know, when I was first typing my etymology blurb I had spelled the Latin word ientaculum, but the I saw another entry that spelled it jentaculum, and since I and j have a lot in common in appearance, I though possibly the bottom of the j got erased or didn't come through, so I went with jentaculum.  Oh well, so much for my reasoning ability .

Yeah, the Roman alphabet didn't have the J and the I often took its place. The J didn't come into English print until the 1629 1st revision of the King James Bible and an English grammar book published in 1633. I find it interesting when researching topics that change over time. There are numerous examples of someone taking something that is common today but didn't exist many millenia ago, and assuming today's truths were the same back then. If that makes any sense.

The three or four would mean the 3rd or 4th hour of sunlight, as Romans divided the light and dark parts of the day into 12 equal "hours", which were not fixed. So 3 or 4 hours after sunrise might still be when many eat their breakfast nowadays
