[kuroisaiyajin]

I've been away for a while, pretty sure no one noticed though. Either way, good to be back.

人々 ひとびと people, everybody
日々 ひび everyday, daily
時々 ときどき sometimes, at times
方々 ほうぼう here and there, this way and that way
我々 われわれ we, us

The second symbol goes by a few names, 漢字返し (かんじがえし)、 同の字点 (どうのじてん)、 or のま. I'm not sure which is it's actual name, but I'm sure it's commonly known as のま. It's purpose is to repeat the kanji before it, but it doesn't sound exactly the same. It's not something I'm able to explain, hopefully one of the greats here can shed some light on it.

The first three I hear somewhat often, he fourth I think I've heard once before, never had a good opportunity to use it myself. The fifth is archaic, I believe, I only hear it in TV shows, games and some anime, usually stuff based in feudal Japan. I like hearing 我々は... and so forth. Probably not something to be used in conversation, at least not serious ones.
