What per anum mean?

Answer 1

I believe you meant to say "per annum" (with the word "annum" having 2 n's) which means occuring yearly. The phrase "per anum" (with the word "anum" having 1 n) means, well, you can look that up yourself.

Answer 2

"Per annum" is a Latin term that translates to "per year" in English. It is commonly used in financial and legal contexts to indicate an annual rate or figure, such as interest rates, salaries, or expenses. For example, if a loan has an interest rate of 5% per annum, it means that 5% interest is charged each year on the principal amount.
