“Lada” can refer to two main things, depending on context:

• A Russian car brand: Lada is a Soviet/Russian marque of passenger cars produced by the manufacturer AvtoVAZ, known for simple, rugged, budget‑oriented vehicles like the classic Lada Niva and current models such as the Granta and Vesta.

• A medical term (LADA diabetes): LADA also stands for “Latent Autoimmune Diabetes in Adults,” a slow‑developing autoimmune form of diabetes that appears in adulthood and shares features of both type 1 and type 2 diabetes.

If you say whether you mean the car brand or the diabetes type, a more detailed and tailored explanation can be given.
