'make firm, bind'(Modern English fasten)
ME festnen seems to represent OE fæstnian with the vowel of fest (v.). Direct loan from ON is a more problematic possibility in this case (and only suggested by Oakden I.78, McGee 328–9 (who does not include the instance at Pat 273) and GDS (where it is cited alongside the OE etyma)), since no ON equivalent with i-mutation is known; cp. OIcel fastna ‘to pledge’ next to OS, OHG fast(i)nōn < PGmc *fastinō(j)an- (alongside OFris festnia, OHG festinōn).
Proposed ON Etymon (OIcel representative)
cp. fastna ‘to pledge’
Other Scandinavian Reflexes
fæstnian 'to fasten, fix, secure, bind'
Phonological and morphological markers
[i-mutation] (possibly diagnostic)
Both -est- and -ast- variants are attested more frequently in ME than fest. There are a number of early forms with <e> (inc. a1150(c1125) Vsp.D.Hom.Fest.Virg.(Vsp D.14) and Orrm); these recur throughout ME, in a range of dial, though they are perhaps most predictable in N and E texts.
