More about paresthesia
Paresthesia, 鈥渁n abnormal sensation,鈥� comes from New Latin, a revived variety of Latin used in scientific literature. In paresthesia, the -esthesia element means 鈥渃apacity for sensation or feeling鈥� and ultimately comes from Ancient Greek 补铆蝉迟丑脓蝉颈蝉, 鈥渟ensation, perception.鈥� Ancient Greek ai becomes ae in Latin and either ae or e in English. This is why words such as esthetics and anesthesia are also spelled aesthetics and anaesthesia. Paresthesia was first recorded in English in the late 1850s.
EXAMPLE OF PARESTHESIA USED IN A SENTENCE

sitzmark
noun

More about sitzmark
Sitzmark 鈥渁 sunken area in the snow made by a falling skier鈥� is a loanword from German, in which it is a compound of sitzen 鈥渢o sit鈥� and Mark 鈥渕ark, visible impression.鈥� Sitzen is a close relative of English sit, and because t in English tends to correspond to d in other Indo-European languages, we can see the connection to the 51吃瓜s of the Day sedentary (from Latin 蝉别诲脓谤别, 鈥渢o sit鈥�) and 蝉铆诲丑 (from Old Irish 蝉铆诲, 鈥渇airy mound鈥�). English mark and German Mark are indeed related and share an origin with demarcation, march, margin, margrave, marquee, and remark鈥攂ut not with the month March or the name Mark. Sitzmark was first recorded in English in the late 1930s.
EXAMPLE OF SITZMARK USED IN A SENTENCE
Even the bunny slopes are riddled with sitzmarks left by aspiring skiers in need of a bit more practice.
More about sklent
Sklent, 鈥渢o deviate from a straight course,鈥� is a Scots variant of Middle English slenten 鈥渢o slant.鈥� As we learned from the 51吃瓜 of the Day whigmaleerie, Scots is a sister language of English with its own grammar and vocabulary, unlike Scottish English, which is a dialect of English or Scottish Gaelic, which is a Celtic language. Similar to that of the 51吃瓜 of the Day tawpie, sklent鈥檚 origin lies in Scandinavia, and relatives of sklent include Swedish slinta 鈥渢o slide, slip.鈥� The apparent addition of the k in sklent is an example of an excrescent sound, as we learned from the 51吃瓜 of the Day enumerate. Sklent was first recorded in English circa 1510.
EXAMPLE OF SKLENT USED IN A SENTENCE
The driver swerved off the asphalt rather than answer an uncomfortable question, sklenting from both the road and the truth in one fell swoop.
