What on earth is a caulk? If you're part of the 90% who were left confused by today's wordle, fear not. You're not on your own here.
Ever since The New York Times acquired Wordle from its original creator, Josh Wardle, there's been a few tricky selections for the five-letter puzzle.
Today's proved to be no exception. Many were left bemused putting the letters into the grid and finding five green squares appear despite not knowing what it means.
A caulk, according to the Cambridge Dictionary, is a substance used for filling in the gaps around the edge of something, for example, a bath or shower.
Caulking is also a widely used term that is used when you make something tight against leakage or to stop something from breaking out.
Those who are in the building trade or a dab hand at plumbing or maintenance might have been more familiar with the context of today's wordle.
Builders or bathroom specialists might use a caulking gun to apply caulk along a set of tiles or a gap in a skirting board, for example.
The word has derivatives from the French and Latin languages. It's a variant of cauchier and calcare which means to 'tread' or 'press with force.'
However, caulk is not to be confused with prominent Sierra Leone defender and former Liverpool man Steven Caulker, who just so happens to share the letters.
Caulker most recently represented the Sierra Leone side that went to the African Cup of Nations, as he qualified through his paternal grandfather.
There is no evidence to suggest that Steven Caulker can caulk, nor does he have a caulking gun of any sort. We wouldn't want to jump to conclusions.
After it's all said and done, at least we might be a bit more familiar with building terminology and appreciate its place in the English language.
Let's hope future Wordle's aren't as tricky or frustrating. A lot of 5 out of 6 and 6 out of 6 attempts were had today as a result.
