は — contrastive and emphatic は
Meaning
- as for ~ / (in contrast) ~ — beyond marking the topic, は singles one thing out against an implied alternative, or limits the scope of what is asserted
On top of its basic topic role, は carries an implicit *contrast*: saying X は flags that something else may differ. ビールは飲みます hints 'beer I'll drink (other drinks, maybe not)'. In negatives it narrows the scope of the denial — そんなに高くはない is 'not *that* expensive' (it is somewhat), softer than a flat 高くない. Placed after another particle (には, では, とは) it adds this same contrastive, limiting colour.
Key sentence
Usage

Notes
- Pronounced わ as a particle though written は. The contrastive reading is context-driven: the same は is plain topic or pointed contrast depending on intonation and what alternative is implied.
