We’ve been noticing this graffiti all over town.

Here’s the latest, scribbled on the wall of St Canice’s catholic church on Roslyn Gardens, near the corner of Roslyn Street.

UPDATE: Thanks to @alliejt‘s keen eye, we’ve got another clue.

So now we’ve had:

A is for “azimuth”
C is for “cephlapod”
K is for “kibosh”
M is for “modulate”
N is for “nebulous”
Z is for “zipper”

Is it a riddle?
