1. Illinois
Geography & Places · US State Abbreviations
Midwestern state admitted as the 21st state on December 3, 1818. Springfield is the capital, where Abraham Lincoln practiced law, while Chicago, the third-largest US city, dominates the state's population and economy; the Prairie State's license plates carry the slogan Land of Lincoln.
Example: Her W-2 listed a Chicago, IL address even though she worked remotely from Wisconsin.
Illinois is shortened to Ill. in AP datelines and labels such as D-Ill. The two-letter IL was adopted in 1963; newcomers sometimes write IN, which is Indiana, or IS. IL is also the ISO country code for Israel and its .il domain. Because Ill. looks like the word ill, headline writers often spell the state out.
2. Israel
Geography & Places · Country Code Abbreviations
Israel's code, alpha-3 ISR, with the new shekel trading as ILS and websites on .il. The government sits in Jerusalem, although most countries keep their embassies in Tel Aviv because of the city's disputed status.
Example: The startup's .il website switches to English for visitors outside IL.
In US addresses IL is Illinois. The language code for Hebrew is he; older software used iw, which some systems still accept. Israel is a major center for cybersecurity and semiconductor research.
3. Injured list
Sports · Baseball Abbreviations
MLB roster list for injured players, who do not count against the 26-man active roster. Position players go on the 10-day IL, pitchers on the 15-day IL, and long-term injuries go on the 60-day IL.
Example: The Dodgers placed their ace on the 15-day IL with elbow inflammation.
Renamed from the disabled list (DL) in 2019 to avoid stigmatizing language. Players on the 60-day list also come off the 40-man roster. In the NFL the equivalent is injured reserve (IR). In geography IL is the postal code for Illinois.
4. Intralesional
Medical · Medication Route Abbreviations
Injection of a drug directly into a skin lesion or tumor, such as triamcinolone into keloids, alopecia areata patches or acne cysts, candida antigen into warts, or talimogene laherparepvec (T-VEC) into melanoma.
Example: Kenalog 10 mg/mL 0.1 mL IL to each cyst; return in 4 weeks.
Intralesional steroids concentrate the drug where it is needed with little systemic absorption, though skin thinning and lightening can occur. The term overlaps with "intratumoral" for oncolytic virus therapies. IL also means interleukin, as in IL-6 inhibitors, which is far more common in modern literature.
5. Impermanent loss
Technology & Computing · Cryptocurrency & Blockchain Abbreviations
The shortfall a liquidity provider suffers, compared with simply holding the tokens, when the prices of the pooled tokens change relative to each other. It becomes permanent if the provider withdraws before prices return.
Example: ETH doubled while I was in the pool, so IL ate most of my fee earnings.
The loss grows with the price divergence: a twofold change in one token's relative price causes about 5.7 percent loss in a standard 50/50 pool. Pools of stablecoins or closely correlated assets suffer little of it, and trading fees may or may not make up for it. IL is also the postal abbreviation for Illinois.
