The english words ‘historic’ amd ‘historical’ sound entirely familiar to native greek speakers. Derived from ancient, classical greek, they are adjectives stemming from the abstract noun ‘history’, a word that entered the English language in 1390 with the meaning of "relation of incidents, story''.
However, when it comes to their use, we are all on the horns of a dilemma. Is 'historic' synonymous with 'historical'? The answer is no. Historic means "important," "momentous," or "historically significant." Historical means "relating to the past."
