Alike

I think the word "alike" is simple, but very pretty, so I wanted to see where it comes from.
It is actually a blend, coming from the Old English words anlich (from OE onlic) and ilich (from OE gelic). This blend was later influenced by the Old Norse word, alikr to become the middle English alich.

The definitions given by the AHD include;
1)Resembling closely;similar.
2)In the same manner or to the same degree.

To further elaborate on the Old English words, here are some definitions from Albert Cook's The Old English Elene, Phoenix, and Physiologus:

Onlic-Super
Gelic-like, similar
