Achar is the Hindi and Urdu word that’s attached to the main ingredient. The words in other languages are different - athanu in Gujarati, for example.
But also, some pickles have standalone names (without the word for pickle attached). The marmalade-y ones I referenced above, for example, are just “chhunda” and “murabba”— no achar/athanu in the name. And I recall a couple of types of spicy mango (chunk) pickles that also had unique names, without the word pickle.
(Chutney is a common word across several (north/west regional Indian) languages, though. There are other words in the east and south. )
