<p>Which is correct? “He was experienced in the ways of the military” or “He was experience with the ways of the military”</p>
<p>It should be “experienced in” in this case. I’m horrible at remembering grammar rules, but I think “experienced in” is used when talking about a large concept, “experience with” when referring to a more specific noun. </p>
<p>You can either say “He was experienced in the ways of the military” or “He had experience with the military”. In the first phrasing, the person is very familiar with the military, whereas for the second one, not so much experience.</p>
<p>^What he said.</p>
<p>In “He was experience with the ways of the military,” ‘experience’ is a noun. The ‘was’ requires ‘experience’ to be an adjective, which it is not.
In “He was experienced with the ways of the military,” ‘experienced’ is an adjective.</p>
