Excerpt from the book
"A friend of ours was talking to a theatrical agent who was not particularly distinguished for the range of choice of his vocabulary."
I have consulted the online Merriam Webster, but none of the meaning (according to me) describes the meaning of distinguished in the above given context.
- marked by eminence, distinction (see DISTINCTION sense 5), or excellence
- befitting an eminent person
I personally think that "distinguished" in the above context means "known for".
Can you help me understand the meaning of the word in the given context?
