Your right, the usage in the title is wrong. And so is it in the previous sentence. Sue me!
I actually do care and do sometimes notice when I screw up. Most of my errors are sloppiness rather than ignorance. Some things just irk me. For example, I think the quotation mark outside the punctuation is aesthetically displeasing. An Englishmen is rumoured to have said “that’s how we do it in the old country”.
Anyway, I saw this shirt on the internet and had to laugh:
Kevin Kim, if I knew where to buy one you’d be wearing it proudly. So their!
From a grammar Nazi’s perspective, what’s really interesting about that shirt is that the swastika is composed entirely of parts of speech instead of explicitly grammatical terms! Parts of speech represent the words, i.e., the building blocks of utterances, whereas grammar is, more precisely, the structure into which we insert those building blocks to make our utterances. (See here.)
It might have been better had the shirt sported terms like
•subject-verb agreement
•case (nominative, accusative, dative, genitive)
•mood
•word order
•tense
•indicative
•interrogative
•subjunctive
•conjugation
(etc.)
Nice try, Shirt People!
HaHa! You are the King of the Grammar Nazis!
