Traditionally, the possessives of classical and Biblical names ending in s, such as Archimedes and Jesus, are written without a final “s”.This can lead to confusion, especially in print, since in this case, s’ it is not indicating a plural noun.
- Archimedes’ Principle
- Jesus’ disciples
For current usage, the above rule (for example, with regard to the Spanish given name Jesus) does not need to be applied as it is not occurring in a Biblical or classical context.
- This is Jesus Ramirez, and this is Jesus’s wife.
Please see also Usage notes for ’s for further clarification.
- As in the example sentences, the string to be replaced and the string replacing it are surrounded by slashes. Often, the second string is followed by a g; see etymology, above.
This comes from the command s, originally in ed but found in Perl, to replace one string with another. Although the command does not require slashes — other punctuation can be used — in this informal (i.e., outside of scripting) verb slashes are virtually universally used.
In the original command, a trailing g means that the change in strings should be effected every time the first string appears (not just the first time it appears); this g is often used in this informal verb also, as described in the usage note below.
