Having freckles; marked with freckles or small brownish spots on the skin.
From 'freck' (the original form of freckle) plus the past participle or adjectival suffix '-ed'. In older English, '-ed' marked both past tense and adjective forms derived from nouns.
Older English used '-ed' much more broadly than we do now—'frecked' means 'having freckles' the same way 'talented' means 'having talent,' showing how one suffix can do double duty.
