What does postfixing mean?
Postfixing is the act or process of adding an ending to a word, name, or other symbolic expression. The added element is called a suffix, and it usually modifies the meaning, grammatical function, or technical role of the original form. For example, adding the suffix -able to a verb can create an adjective, while adding a numbered ending may help distinguish files or database records. The term can also refer to the suffix itself. Postfixing is relatively uncommon in everyday English, which more often uses suffixing, adding a suffix, or attaching an ending. It nevertheless remains useful in linguistics, computing, standardized notation, and other fields where precise descriptions of how forms are constructed matter. Its name reflects the position of the added material: it is placed after the base form, in contrast to prefixing, which places an element before it.

Where does postfixing come from?
Postfixing is derived from postfix, a word formed from the prefix post- meaning 'after' and fix in the sense of 'fasten' or 'secure'. The form ultimately draws on Latin postfixus, meaning 'fixed after'. It developed in parallel with prefix and suffix, all describing the placement or attachment of an element within a larger word.
