1) I have seen some words marked : (Both NAmE, Both BrE), what are they supposed to mean?
2) Some words (meaning, for example) is marked "uncount and count" noun (u,c), so when to use which?
Ex: 1) meaning (of sth) [U, C] the thing or idea that a sound, word, sign, etc. represents:
What’s the meaning of this word?
Words often have several meanings.
‘Honesty’? He doesn’t know the meaning of the word!
"Noun American English [spelling], both spelling used in BrE".... but some words have Both NAme marks whlist some have Both BrE marks... If they mean that "used both in American English and British English", why don't they use unanimous signal?
I know, but why don't they use an unanimous signal like:" Both BrE and NAmE"?
I'm not sure I've completely understood your question, but "Both BrE and NAmE" is ambiguous.
It could mean that both spellings are used in both countries, but it could also mean that only the latter spelling is used in both countries.
But I don't understand the mere "Both NAmE" and "Both BrE" into the bargain. I know that there are two countries in North America both speak English are Canada and The US, but how about the Brtitish English? "Both spelling used in British English?
And what does "noun American English [spelling]" means?
