Hi Jupiter,
I think you shoud write:
One should learn a new word every day. (a) (a = one)
One should learn new words every day. (a) (general meaning)
everyday (one word) is an adjectif and is used only before a noun.
Ex:This dictionary is for everyday use. (everyday = ordinary, happening every day)
Every + singular noun (countable)is an adjecif and is used to refer to all the members of sth.
So, every day in (a) means all days.
You can also say:
One should learn new vocabularies every day.
One should learn a new vocabulary every day.
only if you are genius in linguistics.
The reason is that vocabulary is [color=red]all the words in a particular language. So, if you say:
I learn a new vocabulary every day.
that means:
I learn all English words in any fields one day. Another day,I learn all French words in any fields.
Can you do that?

Ps: In short:
-
Vocabulary: [color=red]All the words in a particular language.
Word: Article (a, an), adjectif, adverb, conjunction, …
So,
How many words are there in this sentence?
This is an interesting book.
First step: Please list:
Article: This, an
verb: is
adjectif: interesting
noun: book.
Second step: only count.
Article: This, an (2 words)
verb: is (one word)
adjectif: interesting (one word)
noun: book. (one word)
Thus, in this sentence, there are 2+1+1+1 =5 words.
These 5 words is a part of your English vocabulary.(because your vocabulary is all of your English words).
- This is a kind friend.
Do the same way, you’ll know this sentence has 5 words.
“a” in this sentence is an article, so “a” is also a word.
A word can include one or more than one letter.
Ex: “a” in this sentence is a word including only one letter.
“this” in this sentence is a word including 4 letters (t,h,i,s).
