> English prides itself on not having diacritics, or accents or whatever that thing where you merge a A and E is called, unless they are borrowed

Its called the letter “ash” and its borrowed from... (Old) English. Though its functionally reverted to being a ligature, which is what is was before it was a letter.

(Also, English has &, which was a letter even more recently—its current name being taken from the way it was recited as part of the alphabet [“and, per se, and”], including the effect of slurring with speed—and which also originated as a ligature.)
