The W Sound in the Germanic Words of the Early French Speakers

Early French speakers had the same type of problem with the W sound. They couldn't quite pronounce it at the beginning of a word. So when they began to borrow Frankish words they had to find a way to mimic that W sound. And they did that by converting the sound to a GW sound, gua which was spelled GU because the letter W didn't exist yet. But even though that G sound may have been pronounced very subtly at first that original pronunciation was lost on later French speakers. Eventually the G was given its normal hard pronunciation in those barred words.
