Persistent Laravel data filters across multiple views

I am writing a multi-language dictionary app. When the user selects a language to use data from, that language should apply to every page until they select a different language. Ideally, the language should be part of the URL so that the address for the English word "double" and the French word "double" is different. It should also be possible to specify no language, so that "double" would display both the English and the French word. I will also want to filter the data on multiple fields at the same time, e.g. the word itself and the language.

I'm trying to fit this into the Laravel resource concept. The index view of Word should show all words filtered by the language, or not filtered if no language is specified. create should keep the language from index. store should just use the form data. The language can be included as a hidden field in the create view if it's been specified. show doesn't strict speaking need a language filter, but if the user then goes back to index, the filter will still need to be applied.

I started using routes, but that means I'll have to hard-code a route for every filter. I've also thought of using session data, but that means the URLs wouldn't include the filter. If the filters are appended as a query string how would Laravel access them? Is this a good solution?

I'm using Laravel 5.8. What's the best Laravel way to persist this type of data filter across views?
