String 将字符串中的字母拼成一个列表

我怎么能把一个单词的字母拼错呢。例如，示例进入

{“e”、“x”、“a”、“m”、“p”、“l”、“e”}

使用AppleScript。我无法添加我尝试过的内容，因为我不知道从哪里开始

items of "example" -- {"e", "x", "a", "m", "p", "l", "e"}
characters of "example" -- {"e", "x", "a", "m", "p", "l", "e"}

text 4 thru -1 of "example" -- "mple"

reverse of items of "example" as text -- "elpmaxe"

set text item delimiters to "e"
set ti to text items of "example" -- {"", "xampl", ""}
set text item delimiters to "f"
ti as text -- "fxamplf"
