"The high status of poets within Celtic societies is well attested and was maintained down to the seventeenth or eighteenth centuries. In Gaelic societies the name for a poet, file (or filid - plural), is derived from a root word meaning "to see". [sic] Celtic poets may be better known as bards and though the Irish and Scottish peoples poets also came to be known as either file or bard, originally there was a distinction in rank between the two with the hereditary file having the higher status and greater training." --on Celtic poetry from The Poet's Garret.
