Nichijō kaiwa sura obotsukanai noni, mashite bijinesu kōshō nado dekiru wake ga nai.

I can barely manage daily conversation, let alone business negotiations.

Jibun no namae o kaku no sae okkū na noni, mashite ronbun o shippitsu suru nado tōtei muri da.

I find even writing my own name to be a hassle, much less writing a thesis; it's simply impossible.

Shitashii yūjin ni sae ienai himitsu na no dakara, mashite shotaimen no hito ni hanaseru hazu ga nai.

Since it is a secret I cannot even tell close friends, much less could I speak of it to someone I'm meeting for the first time.

Kinō wa aruku koto sae mamanaranakatta. Mashite hashiru koto nado omoi mo yoranai.

Yesterday, I could barely even walk, let alone think of running.

Ichiryū no puro de sae tekozuru sagyō na no dakara, mashite shirōto no watashi ni dekiru hazu ga nai.
