8. d′
§ 400. d′ corresponds in formation to t′ but is voiced. A somewhat similar sound occurs in such English words as ‘individual’ when not pronounced with dʒ.
§ 401. Initially d′ represents O.Ir. d before e, i, or preceding r, l, followed by these vowels, e.g. d′αləg, ‘thorn’, O.Ir. delg; d′αrəməd, ‘forgetfulness’, O.Ir. dermet; d′er′uw, ‘end’, O.Ir. dered; d′iə, ‘God’, O.Ir. día; d′ĩ:wi:n′, ‘single’, M.Ir. dímáin; d′l′iuw, ‘law’, O.Ir. dliged; d′ɔ:r, ‘tear’, M.Ir. dér; d′r′eim′ir′ə, ‘ladder’, cp. M.Ir. dréimm; d′r′iʃɔg, ‘briar’, O.Ir. driss; d′u:Ltuw, ‘refuse’, O.Ir. díltud.
The eclipsed form of t′ is also d′, e.g. to̤guw ə d′i:r′ ə, ‘he was brought round’ (of a sick person); ꬶα: d′r′iən, ‘two thirds’; χUə mwid′ ər d′r′u:r, ‘the three of us went’.
§ 402. Medial and final d′ in native words arose from an earlier dd standing before e or i which in O. and M.Ir. was written tt, t. This dd represents i. Prim. Keltic dd in k′r′ed′əm, ‘I believe’, O.Ir. cretim, Welsh credu, Sanskrit šrad-dhā‑. ii. Prim. Keltic nt in m′eid′, ‘size’, O.Ir. méit, Welsh maint; fwəid′, ‘patience’, O.Ir. foditiu from fo-damim; b′r′eid′i:n′, ‘rag’, M.Ir. bréit. iii. Prim. Keltic zd in kyd′, ‘piece, share’, O.Ir. cuit; mwæd′ə, ‘stick’, cp. M.Ir. maite, matan, Engl. mast; ʃeid′uw, ‘to blow’, M.Ir. sétim.
§ 403. In earlier loan-words medial and final d′ corresponds to a Romance or English t which was received as a lenis and later became d′, e.g. bwid′αl, ‘bottle’; in′id′, in mα:rt′ in′id′ə, ‘Shrove Tuesday’, M.Ir. init, Lat. initium; Læd′ïn, ‘Latin’, < Latina; mwæd′ïn′, ‘morning’, O.Ir. matin (acc.), Lat. matutina; pwæd′r′i:n′, ‘rosary’, < Lat. pater; srα:d′, ‘street’, M.Ir. sráit, Norse sráit. Latin words ending in ‑atio appear with ‑ɔd′, ‑æd′, e.g. po̤rəgɔd′, ‘purgative’, Di. purgóid; t′r′ïblɔd′, ‘trouble’, M.Ir. treblait, < tribulatio; ɔ:ræd′, ‘speech’, < Lat. orate, oratio. This ending was also wrongly abstracted from one or two native words such as N′αskɔd′, ‘boil’, M.Ir. nescoit; o̤rəχɔd′, ‘harm’, O.Ir. erchoit and was transferred to English loan-words such as bαskɔd′, ‘basket’; bo̤kɔd′, ‘bucket’; p′ïkɔd′, ‘pick’. b′r′ïŋlɔd′, ‘dream’, Meyer bringlóit, perhaps also belongs here.
§ 404. Occasionally there is confusion between d and d′. M.Ir. drúcht generally appears as d′r′u:χtə; æd′væl′, ‘to confess’, M.Ir. atmail, has been influenced by k′r′ed′væl′; o̤lꬶα:rdəs, ‘re-
