SIL International is a language-focused organization whose name appears as the publisher of linguistic reference materials and software documentation. Its glossary distinguishes concepts such as grammatical tense, which locates a situation relative to a reference time, and grammatical aspect, which describes its temporal presentation.[ref][ref]
Aspect in the SIL Glossary of Linguistic Terms. Definition and progressive example
Its language-technology work includes FieldWorks Language Explorer, software for organizing lexical entries, analyzing texts and describing grammar. An investigator can connect an observed word form with an analysis into morphemes, then compare that analysis across further recorded examples. Such tools make a proposed linguistic morphology inspectable; the stored analysis still needs evidence from language use.[ref]
