T-form

Shifting his feet and still perplexed, he then asked me if I was a faculty researcher, using again the informal T-form.

In the Erzin dialect, children address their parents with the V-form; to use the T-form would show a lack of respect for parents.

Typically, the informal pronominal address term (T-form) is the original second-person pronoun (Latin tu; Germanic du) and the polite or formal V-form is a plural form.
