Hmm. Why should I take this critique as being any more accurate than Bryson, given that the writer says in so many words:
"[...] I - someone who’s far from an expert at linguistics [...]"
The rather sniffy observation about Wikipedia falls very flat as the book was written 10 years before Wikipedia existed!
In fact Bryson wrote his book a good 20 years earlier than this critique so perhaps this huffy person has resources to draw upon that were not available in 1990.
Not that I really expect Bryson's stuff to dot every i and cross every t - he's a humourist.
