Note 1 — Chapter XI · The Consonant Declensions of Nouns.
Reading edition
The r is intrusive in -groom, as it is in cart-r-idge, part-r-idge, vag-r-ant, and hoa-r-se.
2. The n has been appropriated by the article. Cf. an apron (< a napron), an auger (< a nauger), an orange (< a norange), an umpire (< a numpire).
3. In Mn.E. we say “I request a favor of you”; but in O.E. it was “I request you (dative) of a favor” (genitive). Cf. Cymbeline, III, vi, 92: “We’ll mannerly demand thee of thy story.” See Franz’s Shakespeare-Grammatik, § 361 (1900).
4. Scęððan is conjugated through the present indicative like fręmman. See § 129.
