declare

declare: [14] To declare something is to make it ‘clear’. English acquired the word from Latin dēclārāre ‘make clear’, a compound verb formed from the intensive prefix dē- and clārāre ‘make clear’, a derivative of clārus ‘clear’.
=> claret, clear

declare (v.)

early 14c., from Old French declarer "explain, elucidate," or directly from Latin declarare "make clear, reveal, disclose, announce," from de- intensive prefix (see de-) + clarare "clarify," from clarus "clear" (see clear (adj.)). Related: Declared; declaring.
