FullForms: Abbreviations

Now select any text on your iPhone, tap Share, and look it up in FullForms or add it to one of your lists. Siri does both too: just say "Search FullForms".

FullForms is a fast, free abbreviation dictionary. Search any abbreviation and get the full form, along with its category, region, type and a clear explanation of what it actually means.

And when you want a home for your own terminology, FullForms List lets you build glossaries from scratch: your terms, your definitions, your lists.
