A person who is a vexillophile is a hobbyist who studies flags, or vexillology. This is a new designation and only dates to 1959 when flag enthusiasts formalized the study of flags in his publication The Flag Bulletin.
More precisely vexillology is the study of history and the symbolism that flags represent. But vexillophile is not the least of it.
A vexillologist is who studies flags, and a vexillographer is a person who designs flags. And of course, now there are associations, conventions, magazines, and everything else that can be associated with such a topic.
As with many words the origin is Greek and Roman. In Latin “vexillum” is used to describe a square flag. In Greek “logia” means to study.
“The Georgia flag has changed its design so often that only a vexillophile could appreciate all the iterations.”
“If you want to start a conversation at your next dinner party see who knows the definition of the word: vexillophile.”

Alright and allright are both all right and all wrong. There are many examples of people using alright in written form, some well-known. But use does not make a word legitimate and correctly both should be spelled as two words, “all right.”
Alright is used at times and defended because words like already and altogether are spelled as a single word. Each of these could be used as one or two words, so the defenders of alright have a point. Not a good point, but a point.
What makes this difficult is that when spoken alright and all right are the same. and then there are spellcheckers that might or might not flag alright.
“If we work together and keep pushing ahead, we will be all right.”
“All right, I give up!”
