having a command of many languages
The never-ending discussion. The use of the word 'polyglot' and by extension 'fluent' are inherently vague words; ask ten linguists what they mean and they'll likely give you inconsistent definitions. Like Jeff said, it depends a lot on how proficient you are, that is, whether you have enough capability in a particular language to add it to your list and count it as a language you actively know. If I had to blurt out a figure right now, I guess numbers of three and upwards would count as polyglottery since 'one' and 'a couple' aren't very many, but 'several' seems to come closer to a lot of people who wear the polyglot label. Others say it should be at least four or five. I think Wikipedia describes a person with six languages as being a hyperpolyglot.
Hi Olivier, I can only speak French (along with English) - but if you're OK with that, I'll have coffee with you, Anyway we are in the same country and we can talk about the new party. La République!
