thin

thin: [OE] Thin denotes etymologically ‘stretched’. It goes back ultimately to the Indo- European base *ten- ‘stretch’, which also produced Latin tenuis ‘thin’ (source of English tenuous) and Latin tendere ‘stretch’ (source of English tend, tense, etc). From this was descended prehistoric Germanic *thunnuz, which has evolved into German dünn, Dutch dun, Swedish tunn, Danish tynd, and English thin.
=> tend, tense, tenuous

thin (adj.)

Old English tynne "narrow, lean, scanty, not dense; fluid, tenuous; weak, poor," from Proto-Germanic *thunni "thin" (cognates: West Frisian ten, Middle Low German dunne, Middle Dutch dunne, Dutch dun, Old High German dunni, German dünn, Old Norse tunnr, Swedish tunn, Danish tynd), from PIE *tnu- "stretched, stretched out" (hence "thin"), from root *ten- "to stretch" (cognates: Latin tenuis "thin, slender;" see tenet).
