Well, think of it this way: your spelling is correct because the product is made from dough... if it's made from do, it's not very appetizing...
@Janice Martin Ma'am, you have me seriously wondering. Were you a member of Seniors Forum, before I got "busted"? Your demeanor seems so familiar to me. Perhaps you were one of those back then who disagreed with me only infrequently? Gosh, there were dang few of those! AFADIC, (As Far As Dough Is Concerned), those big Kolache I posted recently are made from yeast dough. Much of my other stuff is mader using Baking Powder. The yeast "rise" seems to be a far more dedicated "science" than the other. My Grandma made huge rye breads, about as big as an automobile tire, routinely. I wish I had been a bit older then, as I would have appreciated more her Herculean efforts. Wonderful-tasting bread, with plenty of Caraway seeds. So, doe is dough, is "do" I guess. Frank
Choosing between two acceptable spellings, is not "being unclear" about the spelling. We are choosing the spelling, that we prefer.
@Frank: Now that you mention it, I've seen a number of references on here to a different Seniors Forum, but I don't know what it is.
I use "doughnut," and have always believed that "donut" was simply a means of reducing the number of letters that a doughnut company had to pay for on a sign. Here's one that I have wondered about: publically versus publicly. I learned to spell it "publically," and never questioned whether that was the correct spelling of the word until autocorrect came along to change it to "publicly" every time I tried to use the word. If "publicly" is correct, as it apparently is, then I don't know of another adverb formed from an adjective ending in "ic" that doesn't use "ally." There may be others, but the adverb form of an adjective ending in "ic" almost always ends in "ically." I also prefer "judgement" to "judgment," but am aware that "judgment" is the correct spelling.
I remember when my daughter was at school in the late sixties teachers overlooked incorrect spelling to a degree. Phonetic spelling was said to be less hindrance to understanding. This has backfired with a return to distortions left to us by our conquerors over the centuries.
Perhaps we are to pedantic about spelling. I believe Shakespeare change his spelling when the mood took him.
And he was not the only one at the time which is hardly surprising considering that language (oral and written) developed constantly, incorporating numerous influences before a certain standard including spelling was established. It reminds me of a character in one of his plays whom he had say: I abhor such fanatical phantasimes, such insociable and point-devise companions; such rackers of orthography, as to speak dout, fine, when he should say doubt; det, when he should pronounce debt,— he clepeth a calf, cauf; half, hauf; neighbour vocatur nebor; neigh abbreviated ne. This is abhominable,—which he would call abbominable: it insinuateth me of insanie: anne intelligis, domine? to make frantic, lunatic. ...which, though ironic, reflects the uncertainty as well as the struggle and search for a more uniform standard of language usage.
...and Costard replied..... O, they have lived long on the alms-basket of words. I marvel thy master hath not eaten thee for a word; for thou art not so long by the head as honorificabilitudinitatibus: thou art easier swallowed than a flap-dragon.
