Conjunctions are words which are used to link clauses which can be either dependent or independent clauses. Somewhere I have seen it's not appropriate to use two conjunctions in a single sentence. Like we have a coordinating and subordinating conjunction, so can't we use them in a single sentence? I think for some kinds of additional information we can use a conjunction even if the sentence contains because.

For example,

I followed her because I was new in the city and didn't know many people there.

Is this grammatically correct or not?

    Your sentence is correct and makes sense, but the rule that there's a limit as to the number of conjunctions you can use in a sentence is not correct. [I would prefer a comma after city, though.]

    Hello, Chandan. (1) As said in the previous comment, there is no rule on the permitted number of conjunctions in a sentence (though over-lengthy sentences are always best avoided). (2) ELU expects linked, attributed references to pronouncements on (especially incorrect) grammar. (3) The sentence you ask about does not present difficulties making the question for ELU; ELL is for more basic questions. Dec 22, 2021 at 19:07
  • Yes, it's fine, but note that modern grammar classifies "because" not as a conjunction but as a preposition.

  • Incidentally, there are in certain constructions limits to the number of consecutive conjunctions.

  • There are style rules against using the same coordinating conjunction twice in one sentence, but it's not a grammar rule. It's like putting "and" between everything in a list is poor style, but not a grammar problem: "I had to do the dishes and process the laundry and walk the dog and then figure out what was for dinner."

There is no rule that says you can only use a single conjunction in a sentence. Your sentence is not incorrect for having both "because" and "and".

Writers use long and complex sentences with multiple conjucntions: Here is a very long example from Lolita

“My very photogenic mother died in a freak accident (picnic, lightning) when I was three, and, save for a pocket of warmth in the darkest past, nothing of her subsists within the hollows and dells of memory, over which, if you can still stand my style (I am writing under observation), the sun of my infancy had set: surely, you all know those redolent remnants of day suspended, with the midges, about some hedge in bloom or suddenly entered and traversed by the rambler, at the bottom of a hill, in the summer dusk; a furry warmth, golden midges.

You can find subordinate clauses such as "when I was three" "if you can still stand my style"; coordinate phrases "entered and traversed", "My ... mother died ... and, ..., nothing of her subsists..."

    Providing they're not consecutive (i.e. immediately adjacent), of course.
