blister: blister: [13] Blister and its now extinct variant blester first appear in English at the end of the 13th century, possibly borrowed from Old French blestre, blostre. It seems that this in turn may have come from Middle Dutch bluyster ‘swelling’, but further back than that it has not proved possible to trace the word.
blister (n.): c. 1300, perhaps via Old French blestre "blister, lump, bump," from a Scandinavian source (compare Old Norse blastr "a blowing," dative blæstri "swelling"), or from Middle Dutch blyster "swelling;" perhaps from PIE *bhlei- "to blow, swell," extension of root *bhel- (2) "to blow, inflate, swell;" see bole.
blister (v.): "to become covered in blisters," late 15c.; "to raise blisters on," 1540s, from blister (n.). Related: Blistered; blistering.

1. blow => bluster.2. blow => blister.3. blast => blister.4. blast + water => blister.5. 谐音“不理水痘儿”。
