Third Isogloss
A third isogloss, marking a consonantal change unrelated to the others, more or less follows the Joret line throughout Normandy and continues through northeastern France. It includes all of Picardy, Wallonia, Champagne, Lorraine and a part of Burgundy.
Germanic /w/ (sometimes Latin /v/ was affected as well) was kept north of the line (written w or v), but became /g/ (written g or gu) south of the line.
- Northern French /v/ ~ French /g/
- Latin vespa / Frankish *waspa (wasp) > Picard Wespe, Norman Vêpe ~ French guêpe (wasp)
- Frankish *wahla hlaupan (S. English well and leap) > Picard, Old Norman waloper (> English wallop) ; French galoper (> English gallop)
- Frankish wahtôn (S. English wake and watch) > Picard Old Norman wait(i)er (> English wait) ; Old French guaitier, French guetter
- Frankish *werra > Old Picard Old Norman werre, warre (> English war) ; French guerre (war)
