Commentary
An affix comes after a word in the Nominative 1st-Case in construction denoting time in the sense of 'this is his habit or endurance'.
The word कालात् is understood here also. तद् = that : सोढम् = जितम् or अभ्यस्तं "endured or habituated". Thus निशा सहचरितमध्ययनं = निशा "reading by night". तत् सोढमस्य छात्रस्य = नैशः or नैशिकः 'a student who is habituated or enured to reading by night'. So प्रादोषिकः or प्रादोषः ॥
