Is it correct to use multiple ORs or NORs correct in a sentence?

Sometimes, in many sentences I feel like using multiple or's for an
either or multiple nor's for neither. Let me give two examples.

1. I am not entirely sure what it is but from my experience, I can say
that, it is either a rare plant or a cactus or a type of mushroom.

2. This thing is neither an insect nor an animal nor a plant.

Are these sentences correct? If not, what would be the right way to
write these?

Then there's the issue of whether you've used an inclusive OR, or an
exclusive OR.

Both are correct (except for the comma after "that", which is wrong).
Repeating the conjunction is an emphatic usage. (In speech, it may
also just be a way to add on a bit that you forgot the first time.)
A normal way to say it without emphasis would be:

1A. I am not entirely sure what it is but from my experience, I can
say that it is either a rare plant, a cactus, or a type of mushroom.

2A. This thing is not an insect, an animal, or a plant.

In both cases, the last comma (the "serial comma") is optional.

I have a question about the use of comma just before a conjunction. I
have seen it in many places but I don't know exactly where such a
comma (e.g. "bla, bla, bla, and bla") is okay and where it isn't.

Also, sometimes I need multiple and's in a sentence.

Tom and Cinderella and Dennis and Doug formed two teams and Harry and
Sally were the judges.

What I mean is:

(Tom and Cinderalla) and (Dennis and Doug) formed two teams and (Harry
and Sally) were the judges.

First team: Tom and Cindrella
Second team: Dennis and Doug
Judges: Harry and Sally

How to write such a sentence properly?

It's not really possible - I don't know if other languages do it better
than English.

The second part - "Harry and Sally" is distinct enough, but the first
part doesn't leap out at you (although you can work out what it probably
means).

The only way really is to rewrite it. Even just re-ordering it makes it
slightly clearly (I think):

They formed two teams: Tom and Cinderella, and Dennis and Doug. Harry


and Sally were the judges.

That's quite a good place to use a comma I think.

(I take this to be the non-technical use of "animal" to mean
"mammal". Technically, insects are animals.)

Or uncertainty about whether you'll think of another item.

If you like fancy words, the repetition of the conjunction is called
"hypersyndeton".

...

That "serial comma" is necessary where it makes the sentence easier to
understand. It's not okay where it makes the sentence harder to
understand, which I think is far less common. Some will tell you that
if the reader's understanding of a sentence depends on a comma, you
should rewrite the sentence.

Some periodicals require the serial comma as part of their house style
and some (probably many more) forbid it. I prefer it, but I'm not a
publishing company.

the Omrud set the following eddies spiralling through the space-time
continuum:

Conventional usage is exclusive irrespective of how many ORs are strung
together. In one of the examples, if it turns out to be a rare plant it is
not a cactus or a type of mushroom.

And why does English lack the conjunction NAND, which has had to be supplied
by logic circuit designers? "A nand B" would exclude the case of both A and
B but allow for either one, or for neither. When strung together in a
longer list it would mean "not all of..." but allow any subset including
the null set.

Okay, but could also be "... a rare plant, a cactus, or a type of
mushroom".

> 2. This thing is neither an insect nor an animal nor a plant.

Not okay, because insects are animals. You can't say "this thing is
neither azure nor blue" because azure is a type of blue.

If you said, "this thing is neither an insect nor a crustacean nor an
arachnid" you would be correct.

I said, it's optional.

That's a bad rule. The best rule is to always use it. The next-best
rule is to never use it. (Some people feel that those should be
reversed.) If you switch from one style to the other, you make it
harder to understand.

First of all, where were you when I wistfully suggested here years ago
that if readers could rely on the serial comma, certain sentences
would be unambiguous?

Second of all, several people told me that consistent use or non-use
of a serial comma wouldn't make anything easier to understand for
them, and well-judged inconsistency might make things easier. Where
are they now?

Third, what I wrote was not an overall rule, and what you snipped
modified it considerably. Here, if you like, is a rule that's
compatible (or almost) with what I wrote and contains something vital
that your rule leaves out:

Always use the serial comma. If you find that the resulting sentence
is hard to understand (including for people who don't use the serial
comma, insofar as you can imagine how they'll read it), rewrite the
sentence.

(The corresponding rule that starts "Never" is also workable, but I
don't like it as much and can't claim it's compatible with what I
wrote.)

E, F, G and H are four mutually exclusive events with P(E) = 0.1, P(F) = 0.2, P(G) = 0.25
and P(H) = 0.3. Calculate the probability of:
a) Either E or F occurring.
b) Either F or H occurring.
c) Neither G nor H occurring.
d) Neither E nor H occurring.

I haven't looked at the 2010 question, but I can assert that the present
question cannot be answered because the joint probabilities have not
been specified.

Or does "mutually exclusive" mean that the joint probabilities are zero?
In that case, the obvious answers are correct.

But the last comma can create an ambiguity and thus had better be avoided
in the two sentences discussed, as the "or's" are apparently inclusive.

To elaborate on Jerry's remark that insects are animals, the sentence
"This thing is not an insect, an animal, or a plant", where the last
comma can denote exclusive "or's", is ambiguous as, in the case of, say,
a beetle, it could be answered with "Wrong, this thing is an insect and
an animal, but not a plant" as opposed to "Right, this thing is an insect
and an animal, but not a plant" if the "or's" are taken to be inclusive
(which they can also be if the comma is only meant as serial).

Your "many" suggests that you might be writing overly long sentences.
That's usually a bad idea.

A sentence should use as many as it needs, no more and no less.

A succession of "and"s can sound childishly breathless or grimly
emphatic, or it can drearily indicate that something went on and on
and on.

The general rule is that when you repeat a word, it draws attention to
the word. Whether repetition is a mistake depends on where the writer
wants to direct the reader's attention.
