4.1.3. Contrastive focus
Contrastive focus conveys a new piece of information that contrasts with a previously mentioned item. Contrast is a broad notion that can also appear out of the blue, referring to a larger part of the sentence. However, contrastive focus are pieces of information which deny or correct previous statements. In the example below, sushi represents the contrastive focus and appears before the personal pronoun (ix1)and the verb (adore), which convey background information.
Context: Someone says that the signer likes pizza.
foc
not. ix1 pizzaa ixa ix1 impossible_no_waya. ixb sushib ix1 adoreb
โNo! I hate pizza, I love sushi!โ
Contrastive focus in LIS may also be in sentence-initial position, as shown in the example below.
y/n
A: pizza like ix2
foc
B: ix1 impossible_no_way. sushi prefer
โYou do like pizza.โ โNo! I prefer pizza!โ
Differently from new information focus, which is not frequently accompanied by non-manual markers, corrective focus may be marked by non-manual and manual markers (PRAGMATICS 4.3.1).
It is important to note that corrective focus also allows ellipsis of the background information containing the wrong item. In fact, this is considered a redundant repetition of the previous question or statement and it can be avoided, as in the example below.
A: cake like ix2
foc
B: ix1 not chestnut prefer
โYou do like cakes.โ โNo! I prefer chestnuts.โ
