Nebulous, nonetheless Horace here is right about the pronunciation. Never mind the unstressed final you point out, the two words have different stress patterns. Tinnitus is stressed on the first syllable! TIN-i-tuss. Even in the common mispronunciation you are alluding to, even if it were tin-EYE-tiss, that isn’t quite a good rhyme for arth-RIGHT-issI would have preferred to see it say just that he needs to consult a dictionary, not so specifically a rhyming dictionary.
Right, the stowing-away is imlausible. But to give credit where due, there is the nice coincidence that the Woodstock festival and the Apollo 11 flight were at overlapping times in 1969. A movie based in that coincidence is “A Walk on the Moon” >
Yeah, me too. At first I thought in terms of paper itself, which is sometimes called stock. But that didn’t seem to gibe with the rest of the text.
