### Etymology 1

From Middle English oyle, oile (“olive oil”), borrowed from Anglo-Norman olie, from Latin oleum (“oil, olive oil”), from Ancient Greek ἔλαιον (élaion, “olive oil”), from ἐλαία (elaía, “olive”). Compare Proto-Slavic *lojь. More at olive. Doublet of oleum. Supplanted Middle English ele (“oil”), from Old English ele (“oil”), also from Latin.

** 2013 August 3, “Yesterday’s fuel”, in The Economist, volume 408, number 8847:The dawn of the oil age was fairly recent. Although the stuff was used to waterproof boats in the Middle East 6,000 years ago, extracting it in earnest began only in 1859 after an oil strike in Pennsylvania. The first barrels of crude fetched $18 (around $450 at today’s prices). It was used to make kerosene, the main fuel for artificial lighting after overfishing led to a shortage of whale blubber.
* (countable) An oil painting.
** 1973, John Ulric Nef, Search for meaning: the autobiography of a nonconformist, page 89:Yet, in another way, I was unable to put Picasso's oils in the same class as Cezanne's, or even (which will no doubt shock many readers) as Renoir's.
* (painting) Oil paint.
    I prefer to paint in oil
* (attributive) Containing oil, conveying oil; intended for or capable of containing oil.

** 1884, Trade News, “A one-wheel Nantucket vehicle”, in The Automotive Manufacturer‎, page 372:Such a vehicle is made by taking any old barrel (usually an oil barrel, but the one selected for our sketch was one that once contained Valentine’s varnish) and through each head of the barrel an inch hole is bored, and an iron bar is driven through, leaving the ends projecting about eight inches.

## Middle English
### Noun

oil
* Alternative form of oyle

## Old French
### Etymology 1

From o +‎ il, possibly from:
* Vulgar Latin *hoc ille, from Latin hoc + ille (“this [is what] he [said]”), akin to o je, o tu, o nos, o vos, all ‘this’ constructed with other personal pronouns;
* hoc illud (“this is it, lit. this that”).
In any case, an elliptical phrase of response, by semantic erosion/grammaticalization possibly calqued on Gaulish: compare Portuguese and Spanish isso and eso (“yes, yeah”, literally “this”), Celtic languages such as Old Irish tó (“yes”), Welsh do (“indeed”), from *tod (“this, that”).
Compare with Old French o, ou, oc, ec, euc, uoc, Old Occitan oc (Occitan òc), all from the simple Latin hoc.
