| Remarks | 'Jack', from Middle English 'jacke' from 'Jacke', i.e., nickname for Johan (p. 644, Ref. 11978); 'black', from Old English 'blæc', of obscure origins but probably related to Latin 'flagrare' and Greek 'phlégein', i.e., burn, from Indo-European 'phleg-, bhleg-' (p. 65 in Ref. 11979). Also Ref. 276, 13442. |
