értesz
Értesz is a verb form from the Hungarian verb érteni, meaning “to understand.” In standard modern Hungarian, the second person singular present tense is formed as érted (you understand). The form értesz is not the usual standard form in contemporary usage; it can appear in dialectal, archaic, or nonstandard contexts, and is generally considered nonstandard in formal writing. The presence of értesz as a second person singular present is sometimes noted in discussions of older texts or regional speech, but it is not part of the modern normative conjugation.
In standard Hungarian, the present tense conjugation of érteni is: én értem, te érted, ő érti, mi
Usage notes: érteni with the second person singular in questions or statements is normally expressed as érted.
