What does すら mean in this sentence?


> 気持ちは分かるがお主はもう既に このわしすらしのぐほどの力を身に付けてしまっておるからのう｡

この場合の「すら」は「より」と同じ意味ですか？




すら has the same meaning as さえ, but sounds more old fashioned/stiff. It can
replace を, which is what it looks like it's doing in this sentence. For
example:

> これを読めば分かる。  
>  If you read this, you would know.

> これさえ読めば分かる。  
>  If you just read this, you would know.

さえ shows a minimum example. In your example, it would be similar to the
english "even".

> 気持ちは分かるがお主はもう既に このわしすらしのぐほどの力を身に付けてしまっておるからのう｡  
>  I understand how you feel, but you have surpassed even me in power.

より would not make sense in this context. しのぐ is a verb and cannot come after
より. Like the examples above, すら is replacing を, which would have marked the
object of しのぐ.
