and [face=spionic]i)enai [/face]
are the same word
As for the differences... hmm...
has a futur meaning, 'I will go' . The basic meaning is 'to set yourself in motion', but it has many other meanings depending on which other words it is combined with (a genitive participle, an accusative, a futur participle and so on...).
has many meanings too, come and go, so it's about arriving and leaving, coming home and departing, not about just walking but always going to or away from something. But that's just the 'simple' meaning of the verb, you can combine it with loads of other things to mean different things, e.g. + gen. for a place, or +dat. for person and so on and then the word takes on different meanings. Eimi is used as the future.
seems to mean to come and go too, but I always think of it as more 'walking' in the mechanical sense than erxomai, because it also means 'to make a step' originally. You can also combine it with eimi : [face=spionic]bh~ i)e/nai[/face]
- he stepped to go -> he walked fast
is related to [face=spionic]bai/nw [/face]
but instead of meaning to come and go it's mostly just the mechanical walking.
I don't remember ever coming across [face=spionic]ki/w[/face]
, but my dictionary tells me it's just a poetical way to say to walk or leave.
might be related to serpent (anyone have an etymological dictionary for ancient greek? I think it's very likely
) and originally means to crawl or creep.
got to go now, I'll come back to this thread later though...
