What do the seasons mean?

It's the last day of Summer, and a question came to my mind; In Greek, every season has a meaning:

Άνοιξη    - ανοίγουν τα λουλούδια // the flowers 'open'
Καλοκαίρι - καλός καιρός          // good weather
Φθινόπωρο - φθήνουν τα οπωρικά    // the fruits 'decline'
Χειμώνας  - χειμα = κρύο,ψύχος    // an ancient word, had to ask mama

But what about the English ones? The only results I get from Google are some ridiculous pages - like what is the inner meaning for me personally and stuff..Come someone explain? Or if they don't have, state it in an answer...

Here are a few snippets from an interesting article by Daven Hiskey.

Winter:

[...] probably comes from the Proto-Indo-European (PIE) *wed, meaning “wet”. Alternatively, it may come from the PIE *wind-, meaning “white”

Spring:

plants springing from the ground [...]

Summer:

[...] a variant of the Proto-Indo-European *sem- meaning “together / one”

Autumn:

[...] it’s thought “autumnus” probably came from an Etruscan word and is possibly related to the Latin “augere” meaning “to increase” [...] and became common in the 16th century, about the same time calling it “fall” popped up as the name for the season.  Before calling the season “autumn” or “fall” in English, it was called “harvest”.

Note 1. Here I'm focusing on word meanings whereas the original article is more wide-ranging and discusses the words' evolution.

Note 2. As discussed in comments this is a brief summary of someone else's work. I don't want to duplicate the entire article here. The only changes from original is the use of bold text to highlight what I think most interesting.
