When you have an apocopic form (e.g. radio (the device) is an apocopic form of radiorreceptor in Spanish), is there a converse term that can be used to say, using the example above, that radiorreceptor is an x form of radio in Spanish?
I suppose I am looking for a sort of linguistic term for the antonym of apocope/apocopic. Is it just “full form”?
Thanks!
