Double for each to linq
<p>Im very new to using linq and having trouble to rewrite the following double foreach to linq query</p>

<pre><code>foreach(var country in europe)
{
    foreach(var europianCountry in unitedKingdom)
    {
        if (country.language == europianCountry.language)
        {
            countries.add (country.language);
        }
    }
}
</code></pre>
