At a Chinese dinner, it's polite for the host to 夹菜 - pick up food with chopsticks and place it in a guest's bowl. The gesture says 'I'm looking after you' and outranks the more individualist Western 'help yourself'. Refusing is fine; thanking is expected.
register
Two rare alternate readings to be aware of: 夹 (second tone) for 'double-layered, lined' as in 夹袄 (lined jacket) and 夹衣 (lined garment); and 夹 - locked into the single Beijing-dialect noun 夹肢窝 ('armpit'). Everywhere else, read jiā.
Components

to clamp; press between
Single ideographic unit. Simplified from 夾 in the 1956 reform; modern 夹 stylises a big person with two small figures tucked under the arms into six interleaving strokes, no longer transparently decomposable. Indexed under Kangxi #1 一 by tradition via the top horizontal that crowns the silhouette.
Filed under radical 一 (yī, #1) by convention. 一 is not a separate component in 夹, so no strokes are highlighted.
