Prefixes are locative words in word formation.
The positional relationship between prefix and root is fixed, always before the root, such as "Lao", "Brother, Lao Niang, Lao Wang, Lao Li, Mouse, Lao Ji and Teacher".
It is worth noting that there are "Ma Lao and Mr Lao" in today's vocabulary, that is, "surname+Lao". We say that the "old" here is located in the back, but it is not an affix. Because when we say "Ma Lao, Mr. Liu", we usually use it to address an experienced old gentleman. Guo said that "this situation is best regarded as a real central morpheme" rather than an affix.
Therefore, taking the prefix "Lao" as an example, we say that if a morpheme can be used as a "prefix", its position should be fixed before the root, and it cannot be changed at will.
