Turn list into text

I was making a block that is like the "say []" block, but it says one letter at a time. Sort of like Undertale? But then, it said a list instead of text.
The list had 1 letter in each item.
How would you convert a list with 1 letter as each item into text?
For example, the list could look like this:
item 1: h
item 2: e
item 3: l
item 4: l
item 5: o

but the text should look like this:
hello

Join input list will do what you want.

that works! thanks
