Etymology Dictionary

HAGGIS,  a dish commonly made in a sheep's maw, of the minced lungs, heart, and liver of the same animal.  (E.; with F. suffix.)   M.E. hagas, hageys, hakkys, Prompt. Parv.   Also spelt haggas, hagges, hakeys; see notes to Prompt. Parv., and to the Catholicon Anglicum, p. 169; also the account in Jamieson.   It answers to the F. hachis, 'a hachee, a sliced gallimaufry, or minced meat;' Cot.   And it appears to have been formed, in imitation of this F. sb., directly from the E. hack, to cut small, of which a common Lowland Sc. form is hag, appearing also in the E. frequentative haggle; see Haggle (1).   And see Hash.   Cf. also Du. haksel, minced meat, and Low G. haks un plüks, a kind of hash or mince.   ¶ The Gael. taigeis, a haggis, is merely borrowed from English; see note on Hogshead, p. 811.
