Is there a verb for "adding something in front"?

I was wondering if there exists a verb that is equivalent to saying 'adding something in front'.

For example, if I have the numbers 1234, then I add in front 9 and I will get 91234.


Solution 1:

I think you're looking for the word prepend, as in

...when I prepend '9' I will have '91234'

You could also use prefix, the verb, but I prefer prepend for your usage.

Solution 2:

I shall say it as follows:

If I have the number 1234, then I prefix 9 and I will get 91234.
