A common way to express the concessive meaning is through the sign glossed same, as in the following sentence.
sq
re
giannia ixa sick same job participate
‘Although Gianni is sick, he goes to work.’
This sentence is a biclausal structure, as revealed by the change in non-manual-marking (raised eyebrows and squint eyes over the sign giannia ixa sick). The same type of analysis can be proposed for the following sentence, in which the change of non-manual-marking signals the transition from the first clause (man short) to the second one.
re
man short ix3 same basketball play
‘Although that man is short, he plays basketball.’
