I’ve always wondered why only certain combinations of letters have ligatures, and not others. For example, the “Fi” (Uppercase F and lower case i) combination or for that matter “ft” etc. there are so many instances where one can have ligatures as the letters collide.
Strangely, I haven’t also understood the use of the “ct” and “st” combinations, here the letters dont collide, yet some fonts provide for these combinations with a very “weird” connection.
Can anyone please explain these phenomena, and the use of the “ct” and “st” combinations.
