Mistakes are a part of being human; not all are quite so obvious as this one!
The Parish Church of Saint Nicholas has stood on the Lisburn Road between Rathdrum Street and Rathgar Street since 1901.
"Rath" means a "circular fort". "Drum" is the Irish word for a "ridge" or "long hill". "Gar" can be translated "rough". So the area would appear to have been a rough ring fort on a ridge.
However, a new street sign has appeared and the name has changed! Now we have a ring fort with "Rum". (While rum in English can be a warming tipple... in Irish is doesn't seem to have any meaning at all.)
Of course the name hasn't changed - just some dozer failed to run a spell check before printing off the new expensive sign! Poor soul - to have your mistake displayed for all to see at the end of Rathdrum Street may be an embarrassing situation - or he/she may not even be aware (yet) of what has happened.
It makes you glad that not all mistakes are quite so public!
to whom all hearts are open,
all desires known,
and from whom no secrets are hidden:
Cleanse the thoughts of our hearts
by the inspiration of your Holy Spirit,
that we may perfectly love you,
and worthily magnify your holy name;
through Christ our Lord. Amen.
