transition of a part of a word to another line

[GeneD]

Let's assume it's a very small piece of paper:

Handwriting is the writ-
ing done with a writing instru-
ment, such as a pen or pen-
cil, in the hand.

What do you call transition of a part of a word to another line? Are there any rules for this? I'm almost 100% sure I've done it incorrectly in the example sentence.

I believe it's called "end-of-line hyphenation".

You haven't exactly done it incorrectly, but it does look weird because the hyphenation would only take place once the text reaches the natural end the line, not after just five or six words as you have done.

I've done a little experiment below to demonstrate.

I don't know if this will work because I don't think the text editor does this but I'm going to try it anyway because what I need is for there to be a dev-
astatingly long word at the end of line 1.
