Ok, I've never made fonts before, but recently I was thinking if it would be possible to create a font that displays different "glyphs" of letters depending on the surrounding letters. This is for a handwritten font I've been wanting to create for a while, but I want it to have multiple styles for the same letters and to adapt to the word being written. Is this possible?

Contextual alternates in OpenType features might do the trick

You mean ligatures?
