I have had to write an erratum (single) to one of my papers recently. I searched the internet and I found out that there are at least three versions as follows:

  1. An erratum to "the title of the paper".
  2. Erratum to "the title of the paper".
  3. Erratum: "the title of the paper".

I chose the pattern number 1, but I was wondering which one of these patterns are more grammatically correct?

When there are more than one error to address in the paper, I suppose there is only one option (Errata to "the title of the paper"). Am I right?

If you want to stick with majority usage, you'll be "more right" if you say "When there is more than one error..." – FumbleFingers Jan 30 '13 at 0:08

Yes, you are probably right, at least according to "The Cambridge Guide to English Usage" where, after a long explanation on words of two or more syllables that end in -um, Pam Peters says:

A few scholarly words ending in -um are found with Latin plurals everywhere in the world, namely addenda, ... , errata, ... , ova.

So, according to that book, you should use errata to pluralize erratum.

However, try asking on writer.SE, too.

Data is the plural of datum and schemata is the plural or schema, but why did those ^%*($@?!! at google and microsoft insisted on using datas and schemas and now we have to use these annoying terms too. – Blessed Geek Jan 30 '13 at 1:15
