Achar right? 'Pickle' is exactly what I'd (white British) call it, and vice versa not be surprised when it was what I was given.
Maybe you're thinking of American 'dill pickle' (where the pickle stands for 'with pickled cucumber') but that's at best just one type, and it's only 'American idea' (rather than 'western') that the preserved cucumber itself is to be termed 'a pickle'.
It is true that most non-Indian/inspired pickles I can think of are whole (or large pieces of) vegetables in vinegar and not a lot else, which looks different I suppose but it's the same preservation method. Nimbu achar 'lime pickle' especially is about as common as mango aam ki chutney in Indian restaurants/takeaways in the UK.
A more significant difference, if you insist, between Indian and 'western' pickle would be the presence of oil. But pickle is the right term, and achar is not a stranger to our plates.
