With Adjectives and Adverbs
The basic formula here is (adj/adv) + atque/ac
He has sense equal to his beauty: parem sapientiam habet atque formam.
He has sense equal to his beauty: pariter sapientiam habet atque formam.
She loves and hates in the same way: aequē amat ac odit.
(likewise with similiter)
Here, the formula is more subtle: use ipse, ipsa, ipsum with a relative clause or ac/atque.
I suspect you are disturbed by the same things which I am: tē suspicor eīsdem rēbus quibus mē ipsum commovērī.
I pray to the same gods as you: prēcor deīs atque te ipse.
The Essential AG: 384 n2
It’s an interesting turn-of-phrase with the ipse because it is the gods which are the same and the res which are the same. ipse being used to express comparison seems fundamentally different to ὁ αὐτός. Very interesting!!
