controversy, laboratory, harassment

While each of these has diverse emphasis, in none does this divergence yield a different sense (with the exception of harassment, in which stressing the first syllable may convey a sense of arrogance).

"Submariner" is different. Although either pronunciation may apply to the same thing, the description of that thing is not the same. SubmarEENer is the crew member of a submarine. SubMAriner is more poetic (and I prefer it) but a little non-sensical, meaning a mariner who is under the sea, by inference; or for lurid literals, () one who is under a mariner.

Which leads to an obvious, but unintended, digression to another topic concerning the usefulness of that loveliest turn of phrase, "Hello, sailor!"

...and from there, to the question: 'though beauty may be useful, can a useful thing be beautiful?

a question sure to go unanswered--unless so identified; and with those last three words, the charm of the first six undone...on and on, 'til the devil takes the soul gone foul with the boredom sprung of endless loops of logic

called "philosophy" in common parlance.
