This word originates from Latin 'declarare', meaning to make clear or to declare. The prefix 'de-' (meaning down or away) combined with 'clarare' (meaning to make clear) forms the meaning of making something clear or known.
Think of 'making clear' ('clarare') something 'down' or 'away' ('de-') — that's why to declare means to make something known.
