Common questions

How does a forensic linguist use dialect evidence differently from idiolect evidence?+

Dialect features place a speaker within a broad regional or social group and support statements about likely origin or background, while idiolect features are used to compare a specific individual's habitual choices against a known writing or speech sample for authorship or identity questions.

What is the difference between dialect and accent?+

Accent refers narrowly to pronunciation differences, while dialect is broader and includes vocabulary and grammatical structures alongside pronunciation. A speaker can share an accent with a region while using vocabulary or grammar typical of a different social group.
