Some confusion about 大概

[stapler]

I often read and hear 大概 but I cannot work out its exact use. According to my dictionary it can be a noun meaning "general idea", an attributive  meaning "approximately" and an adverb meaning "probably". But this doesn't seem to explain the meaning of 大概 when I see it used. For example, I just read a line "他大概很奇怪". In my mind all hear is "He was approximately strange" or "he was in general a bit strange". None of these translations really seem and/or feel appropriate. In fact, I often feel that if I just skip 大概 the sentences I read and hear are more "correct" EG "他很奇怪". Is anyone able to help me understand the meaning/nuance of 大概, and explain its usage?

他大概很奇怪. He's probably a bit strange. Or: He's probably a bit baffled. Depends on the wider context.

It can express a guess or conjecture.

 

他很奇怪。 He's very strange.

他大概很奇怪。 I guess (it's because) he's very strange.

ok that makes a bit more sense. Thanks anonymoose.

"他大概很奇怪" means "他大概觉得很奇怪"。He's probably puzzled.

I'd say Visual Chinese's translation is the right one. 奇怪 as adjective means "stange", but as a verb it means "feel amazed, puzzeld; wonder".
