A preposition.  Sounds important.  You link nouns, pronouns and phrases to other words in a sentence.  Or so that’s what the brightest of them all would have me believe.  Who are you really? What sort of a job is linking?  Your title, although gallant I’ll admit, tells me nothing.  Do you connect? Couple? Join? Do you prepare? Endow? Or outfit?  See how hard it is to know you when described by the unfamiliar and unknown?  Leave that maze of grammatical incomprehensibility, and venture into the joyous world of pleasantry.  It will be much more fun I promise!
