Yesterday I leapt over a shrubbery, twisted my right ankle (mildly), and landed hard on my left knee. Somehow this stiffened the muscle(s) behind the knee. I think of it as a learning experience: like, I never noticed before how strong my habit is of putting my pants on right leg first.
Today I bought a Danish-English dictionary published in 1953/4. To my amazement, it uses aa rather than å; I thought å came in at the same time as ø (former oe) and æ (former ae).
