November 2, 2022 - The word predicate has two grammar-related meanings. One is simple, and that's the one we're treating here. Predicates are usually everything in a sentence or clause that's not the subject. (A clause is a part of a sentence that has its own subject and verb.) They express what is said of the subject, and usually consist of a verb and other stuff that's not the subject.

r/grammar on Reddit: Is "in other words" grammatically correct?
May 1, 2022 -

I'm unable to find anything online. Someone just said it and I thought it sounded strange (even though I've heard it a billion times in my life).

It's like it's treating "Other words" as a compound noun. I'm not a grammarian so I'm just guessing. But "other words would be..." makes sense to me, and "in alternate words" makes sense to me, but you wouldn't use other adjectives like "in further words".

Instead of saying "another approach is," you wouldn't say "in other approaches"

Hard to explain, but it just seems like a strange phrase.

When using “in other words” between sentences, is it necessary to use the form “A; in other words, B” or “A - in other words, B”? Assume A and B are different sentences. - Quora
Answer (1 of 9): Well, if A and B are separate sentences, the thing separating them is a period. “We can expect precipitation. In other words, it's going to rain.” However, because the sentences are so closely related,you can join them into one sentence by using a semicolon.
