The term 'not more than' is used to indicate a maximum limit or amount. It can be expressed in several ways, such as 'JUST', 'ONLY', 'MERE', 'upto', 'atmost', and 'atthemost'. The first four words are four-letter words, while the last two are six and nine letters respectively. All of these terms mean the same thing: not more than a certain amount. They are often used to describe a maximum number of items, a maximum amount of money, or a maximum time limit.
