Looking at the table of contents to Apte's "Student's Guide to Sanskrit Composition (third edition 1890)"  only western grammatical terms are used. Does that mean that the grammar of sanskrit sentences can be correctly  described using western grammatical terms, but it's just that those western grammatical terms don't correspond to Indian grammatical terms for sanskrit.

Link to the ninth edition (reprint of third edition?)
