Today’s word, priodol, means appropriate, proper or suitable in Welsh. I came across it while reading a web page about self-employment and had to look it up as I wasn’t sure what it meant in the context. I knew that the root priod had something to do with marriage, but didn’t know it also meant proper.

Example of usage:

Mae rheolau a gyflwynwyd yn Neddf Cyllid 1994 yn golygu bod angen i chi gadw’r holl gofnodion priodol bellach.
The rules introduced in the 1994 Finance Act mean that you have to keep all the appropriate records now.

There are many more examples in the Llyfrgell Owen Phrasebank.
