I checked it out in a Latin dictionary site and it comes back a little wispy to get translated all by its lonesome.

quasi [as if , just as], esp. in hypothetical comparisons; also with descriptions, [as it were, a sort of];

modus -i m. [a measure , standard of measurement]; in music, [rhythm, measure, time]; in plur., [strains, numbers]. Transf., [limit, boundary; rule; manner, mode, way, method]; 'servorum modo', [after the manner of slaves]; 'eius modi', [in that manner, of that kind].

Modo would be the dative or ablative singular (I think)
