basal
Insulin which caters for the normal base requirements for each day. For MDI this is given as one or more injections per days. Insulin pumps deliver using the basal rate. Also known as background insulin
Basal rate
A rate, normally in units per hour, of insulin which an insulin pump will deliver.
basal/bolus
An insulin treatment method using two different types of insulin and usually consisting of at least 4 or 5 injections a day. Basal (or background) insulin is long-lasting and has a fairly flat, even activity profile designed to deal with the trickle of energy released by the liver throughout the day to fuel the body's background needs. Bolus (or mealtime) insulin is rapid-acting and is given before eating to allow the body to process the energy (carbohydrates) in food and snacks.

A blood test carried out at clinic which shows how much glucose has been in the bloodstream during the last 3 months. Glucose sticks to red blood cells, so the more sugar travelling around in your blood, the more sticks to the red blood cells.

hyper
Hyperglycaemia - high blood glucose. People with diabetes are generally advised to aim for blood glucose no higher than 9mmol/L by 2 hours after a meal. Everyone, whether living with diabetes or not, will have fluctuations in blood glucose levels throughout the day. But in the case of type 1 diabetes, those fluctuations are likely to be greater. Symptoms of high blood glucose can include tiredness or lethargy, headache, increased thirst, blurred vision, increased need to unirate. Sustained exposure to high blood glucose is associated with diabetic complications such as blindness, kidney failure and nerve damage. In severe cases high blood glucose in type 1 diabetes can lead to a dangerous condition known as DKA
hypo
Short for hypoglycaemia - low blood glucose. People with type 1 diabetes are generally advised to keep blood glucose above 4. 0mmol/L to avoid hypoglycaemia. Symptoms of hypoglycaemia include hunger, anxiety, pale skin, sweating, shakiness, tiredness, blurred vision or flashing lights, lack of concentration, mood swings. In more severe cases hypoglycaemia can lead to siezure, unconsciousness, coma and death.

Radio Frequency. The way a Rileylink or a OpenAPS rig communicate with a loopable Medtronic pump
rig
The hardware components for the OpenAPS system
Rileylink
A DIY community designed and built device which allows Loop to send instructions to an old Medtronic insulin pump

Roche
Maker of, amongst other things, the Accu-chek Combo and Insight insulin pumps, which can be used with AndroidAPS

rtCGM
Real-time Continuous Glucose Monitor . In my view it's not a required term as CGM results should be sent continuously. rtCGM only seemed to be coined when people started referring to Freestyle Libre and CGM, which confused some.
Ruffy
An early experimental release of open source software that allows your Android mobile phone to communicate with Roche AccuChek pumps

safe mode
Part of the algorithm for the MiniMed 670G. When in 'auto mode' if irregularities in sensor signal or values are detected the pump can temporarily enable a safe mode which uses a flat basal profile based on the users previous recent basal requirements. The maximum time in safe mode is 90 minutes.
SAGE
Sensor Age - How many days a sensor has been active. Shown on Nightscout sites
set
SGV
Sensor Glucose Value - glucose value derived from a CGM source
Share
Refers to Dexcom Share, where data from certain Dexcom systems is sent to and stored on Dexcom servers. This can be use with their Follow apps, plus Nightscout (etc. ) can pull data from these servers.

split bolus
Another name for a multi-wave bolus but also used in MDI when more than one bolus is done for a meal
square-wave bolus
An extended bolus for Medtronic pumps
External links:
SSH
Secure Shell is a way of connecting to an OpenAPS rig
standard bolus
A pump bolus which delivers an amount of insulin immediately
superbolus
A normal bolus but with the addition of an amount of units 'borrowed' from the forthcoming basal, which is then set to 0 for the period borrowed. As an example, if basal is 1u per hour and a food bolus is 5u, for a superbolus you could borrow 1u from the forthcoming hour's basal, to give 6u up front, and putting on a zero-temp for one hour.

TBR
A temporary basal rate set for a period of time. At the heart of all DIY closed-loop systems which often set TBRs which last for 30 minutes
TBRs
Not one TBR, lots of them
temporary basal
see TBR
temporary target
A different target BG range which is set for a duration of time. All closed-loop systems will use this as the new target BG range until the duration is reached, after which it reverts to the normal target
tethered pump
A standard insulin pump with a tube for the insulin
tethered pumping
Use of a low dose of basal insulin alongside pumping to reduce the risk of DKA in the event of pump failure.
See also:
tethering
Usually refers to Bluetooth tethering but might also be referring to tethered pumping
Time In Range
See TIR
TIR
Time in Range - A percentage of how much time you have spent in your personal glucose target range. People using closed loop systems are often proud of their high percentage and feel this gives a better indication than HbA1c
Trans am
A single-use waterproof Libre reader, part of the Blucon range from Ambrosia Systems
External links:
UAM
Un-announced Meal. From the OpenAPS guide "UAM provides an alternative method (in addition to or instead of carb entry) for detecting and safely dosing insulin in response to significant BG rises, whether they are due to meals, adrenaline, or any other reason. ". It may also refer to an OpenAPS prediction line

unicorn
Unicorns are precious, firstly because it can mean when your BG hits 100mg/dL or 5. 5mmol/L; it can mean when your CGM reading is exactly the same as your BG meter; lastly though unicorns feature in many of Dana M Lewis's presentations about looping, plus they appear on the Explorer Hat. So, as Dana once said "Unicorn: because, why not"
Urchin
Urchin is a watchface which displays lots of the information loopers with OpenAPS like to see, such as the CGM graph, the TBRs and projection of future BG level
