二、true的用法

1、true

2、true: [OE] The underlying etymological meaning of true is ‘faithful, steadfast, firm’; ‘in accordance with the facts’ is a secondary development. It goes back to the prehistoric Germanic base *treww-, which also produced German treue and Dutch trouw ‘faithful’ and the English noun truce, and it has been speculated that it may ultimately have links with the Indo- European base *dru- ‘wood, tree’ (source of English tree), the semantic link being the firmness or steadfastness of oaks and suchlike trees. Truth [OE] comes from the same source, as do its derivative betroth [14], its now archaic variant troth [16], the equally dated trow [OE], and probably also trust and tryst.=> betroth, troth, trow, truce, trust, truth, tryst
