n.公共；共性；老百姓
Low birth weight infant is a primary commonality health problem in the world. 低出生体质量儿是世界上一个主要的公共健康问题。
I found that it did not have any commonality with the immortal. 我没发现它与仙人有什么共性。
This needs to be explained to the commonality so that they will not be confused either. 这种情形，还要对老百姓讲清楚，不要把他们弄糊涂了。
