Dear writers:
Putting "And also," or, "And plus" in a sentence is just saying "And And," or, "Plus Plus."
This does not mean you can not have those words in the same sentences. Let me explain with an example.
"Sally would like a sandwich, and she also likes grapes."
"Sally would like a sandwich, and she likes grapes too."
^ These are incorrect. You basically said "and she and likes grapes." Which makes no sense. It would be grammatically correct if you took out one of the 'in addition' words. So the sentence would read:
"Sally would like a sandwich; she also likes grapes."
Or
"Sally would like a sandwich, and she likes grapes."
Or
"Sally would like a sandwich; she likes grapes too."
^ This is correct. You executed your sentence perfectly and you said what you wanted to say without any confusion or duplication!
It's not always that way though. Since English is so high maintenance, It differs depending on the way you place the 'in addition' word.
You would not need to change the sentence if it were like this:
"Sally would like a sandwich; she also likes grapes and apples."
Since 'And' is with a subject, it does not need to be removed. Another example.
"Jacob is waiting for Sally at a café. He knows what Sally likes to eat. He also likes sandwiches, apples and grapes."
Be weary of words you put together when they mean the same thing. If not to exaggerate a sentence, it becomes grammatically incorrect and often distracting.
Hope it's not confusing, Lol.
