'mass'(Modern English mass)
OE had the variants mæsse and messe, apparently < VLat *messa (late classical Lat. missa), and cp. OIcel messa, OFris misse, OS missa, OHG missa, messa (and MDu misse, messe, mis, MLG misse, MHG misse, messe). Forms in <e> occur sporadically across all dial of OE (OED3); this would be the regular descendant of VLat /e/, but the majority OE type spelt <æ> is more difficult to explain (see possible explanations in Campbell §208 and Wollmann 1990). Almost all authorities are satisfied that the ME variants of the word, incl. those in <e>, descend from OE, with the possible addition of input from OFr messe (so OED, MED, TGD). A few explain it as a loan from the OF (e.g. Jordan-Crook §32 Rem. 3 following Morsbach, Clark 1952–3: 83), and only GDS cites ON messa as a possible ingredient to explain the vocalism of the ME. But there is no evidence that ON had borrowed the word early enough for its influence to be feasible; it is usually regarded as a loan via either LG (thus de Vries, Mag.) or English (so Gammeltoft and Holck 2007: 148).
