Hi.

quam magnum est in viribus suis latus viri

I ask you about in viribus suis.
I suppose this would be a form of abl. of respect or abl. of standard of measuring,
but in the grammar, I can’t find an example in which the preposition in is added to those abl..
But, if prepositions are such things as are used to specify the meaning of bare case, I think the addition of in is no problem even if the grammar doesn’t mention it…
then, do you think in + abl. can express “in what respect?” or “in what standard ?” ?

in + abl. = “in the case of” (L&S, I.C…“where a person or thing is thought of as in a certain condition, situation, or relation”)

It would be the same to say “great in the case of its powers” or “great in reltion to its powers” and to say “great in respect of its powers”.
But, I can’t find a sample of in used like “in respect of” under the article you mentioned in the in page of L&S,
I can only find what you mentioned, “in hoc homine saepe a me quaeris, etc.,” in the case of, Cic. Verr. 2, 3, 3, § 6:.
This sample and quam magnum est in viribus suis latus viri are quite different in construction, so I’m not sure if I can apply this “in the case of” to the in of in viribus suis.
