I don't see how any of the answers identified a word, they
all identified a string. The other words that might exist
might prove more interesting if they are "I", "II", "III", "IV", "V".
Such questions always come down to knowing your data,
including punctuation and placement.
i.e. Sr Juan Lopez
Harvey Brown, Sr
Not to mention that people have names that look like titles/rank,
but as far as I know they don't abbreviate them.
