は（対比） (wa (taihi)) — は setting two things against each other
This one is like this, that one is not — は used twice.
Formula (सूत्र ढाँचा)
Grammar rule (व्याकरण नियम र परिभाषा)
は can show the difference between two things. The shape is simple: A は ～ますが、B は ～ません. Put は on both sides and join them with が (but). Even without the second half, は hints that something else is different — お酒は 飲みません suggests "alcohol I do not drink (other things I do)". は shows up a lot in negative sentences, because a negative usually hides a contrast. を and が drop and は replaces them; に・で・へ stay and become には・では.

Knowledge check (मिनी ज्ञान जाँच)
Question: 1/3Which correctly joins 「ビールを 飲みます」and 「ワインを 飲みません」into one contrast?
💡 Hint: Drop を for は, and join with が.
を and は never stand together. は on both sides, joined by が (but).
Where does は go to add contrast in 「部屋で 吸いません」?
💡 Hint: で does not drop.
Only を and が drop. で stays and becomes では.
Which sentence carries the hidden sense "other things I do drink"?
💡 Hint: When を drops and は takes its place, a contrast appears.
は says "this one, no", which hints "other ones, yes". A negative sentence usually hides that contrast, which is why は shows up so often.
