Learning the relationship between a diæresis and a diphthong and then seeing that the word diæresis contains a diphthong has rounded out my day nicely, thanks for that.
I enjoyed learning recently that the most common diacritics in Czech are the háček and the čárka. The word "háček" has a čárka followed by a háček, while the word "čárka" has a háček followed by by a čárka!
A "calque" is a word that's been brought from one language into another by translating the individual parts. A "loanword" is a word that's been brought over by just taking the word with little modification.
For example, "calque" is a loanword, while "loanword" (from German "Lehnwort") is a calque.
