Suggests the presence of a ‘connector’ particle (a neuter pronominal form *ed) as an explanation for non-lenition following certain preverbs in compound verbs. Also considers the derivation of certain absolute endings of simple verbs from verb + *ed.
Discusses the etym. of (I) OIr. ed ‘space, distance, interval, etc.' and related ined (later inad) ‘place, spot, position, etc.', and id ‘withe, fetter, etc.', all from basic PIE root *ped- ‘foot’; and argues against C. Marstrander (in BILL: 1471) that achad and machad are compounds of an s-stem with a second element *-edo- from the above-mentioned PIE root.
