Modern definitions and controversies The modern definition of Germanic peoples developed in the 19th century, when the term Germanic was linked to the newly identified Germanic language family. Linguistics provided a new way of defining the Germanic peoples, which came to be used in historiography and archaeology. While Roman authors did not consistently exclude Celtic-speaking people or have a term corresponding to Germanic-speaking peoples, this new definition—which used the Germanic language as the main criterion—presented the Germani as a people or nation () with a stable group identity linked to language. As a result, some scholars treat the (Latin) or (Greek) of Roman-era sources as non-Germanic if they seemingly spoke non-Germanic languages. For clarity, Germanic peoples, when defined as "speakers of a Germanic language", are sometimes referred to as "Germanic-speaking peoples". Today, the term "Germanic" is widely applied to "phenomena including identities, social, cultural or political groups, to material cultural artefacts, languages and texts, and even specific chemical sequences found in human DNA". Several scholars continue to use the term to refer to a culture existing between the 1st to 4th centuries CE, but most historians and archaeologists researching Late Antiquity and the Early Middle Ages no longer use it.
