Foot-Strut Merger Raising Rounding Germanic

Open-mid back unrounded vowel to Close-mid back rounded vowel

The shift from the unrounded [ʌ] to a rounded back vowel like [o] or [ʊ] is often a conservative dialectal feature. Historically, English words with [ʌ] (like 'strut') originally had a rounded [ʊ] which unrounded in the South. In Northern dialects and some Irish varieties, this unrounding never happened, or the vowel shifted back toward a rounded quality.
