More about oleoresinous
Oleoresinous, “consisting of drying oils and resins,” is a compound of oleo-, “oil”; resin; and -ous, a suffix roughly meaning “full of, consisting of.” Oleo- comes by way of Latin oleum or olīvum, “oil, olive oil,” from Ancient Greek élaion (dialectal élaiwon), which derives from elaíā (dialectal elaíwā), “olive.” For the reason why these Ancient Greek words are inconsistent about the letter w, check out the recent Word of the Day oenology. Resin comes via Latin rēsīna from Ancient Greek rhētīnē, of uncertain origin. Oleoresinous was first recorded in English in the mid-1840s.

cistvaen
noun
a prehistoric sepulchral tomb or casket.
More about cistvaen
Cistvaen, “a prehistoric sepulchral tomb or casket,” comes from Welsh cist faen, “stone box, stone chest.” Cist comes via Latin cista, “box, chest,” from Ancient Greek kistē. Faen is a mutated form of maen, “stone,” a Cornish relative of which is also part of the Word of the Day dolmen. In Welsh, as in many Celtic languages, the first consonant of a noun or adjective mutates in a variety of contexts, including in some compound words; this is why the m in maen (pronounced like “main” or “mine”) becomes the “softer” f in faen (pronounced like “vain” or “vine”). Cistvaen was first recorded in English in the first decade of the 19th century.
EXAMPLE OF CISTVAEN USED IN A SENTENCE
While dolmens are aboveground homes for the prehistoric dead, the Celts once used shallow cistvaens as burial pits.
algorithm
noun

Why the Museum of Science chose algorithm
You might think algorithms are reserved for complex computer instructions, but if you've ever followed a recipe when you cook, then you have used an algorithm. To learn more, watch this video from award-winning science communicator Maynard Okereke, better known as the Hip Hop M.D.

More about algorithm
Algorithm is a variant of algorism and ultimately comes from Arabic al-Khwārizmī, which refers to the 9th-century mathematician Muḥammad ibn Mūsā al-Khwārizmī. In this name, Khwārizm refers to an area of Central Asia now divided between Turkmenistan and Uzbekistan. Algorism became algorithm because of the influence of Ancient Greek arithmós, “number,” as in arithmetic. Algorithm was first recorded in English in the 1690s.
