[quote=The Nexerus]
To dominate is not to 'beat thoroughly'. That's an informal, incorrect use of the word.

I now require you to remove that signature of yours, turn in your Grammar Nazi card and prepare for the tar and feathering of shame as your lack of ability and understanding of the English Language is never more obvious than this moment.

verb (used without object), dom·i·nat·ed, dom·i·nat·ing.
6.

And then we ALSO have points 3, 4 and 5 neither of which mean 'Control'

A team "thoroughly beating" an opposing team is to "tower above" and "overshadow" their opposition. Ergo. Dominating is neither incorrect nor informal. So GTF off your high horse and learn English properly next time.

Now I point out that point 3 and 6 ALSO apply to the analogy through the word "predominate"

The example I provided fulfilling the very first, fifth AND sixth definitions.

The lesson here Nex, English is a Complex Language. Before you try telling other people what it means, make sure you actually do know what it means.
