拣:select, pick
1) select a kind of thing among things according to some standard.
e.g. 他的男朋友只拣重活干,把轻松的工作都留给了她。
2) equal to "捡"
e.g. 今天我在马路上捡 / 拣到一个钱包。
选: select
when 拣 means "select", it means that someone "selects" something on purpose. Whereas 选 means just "select". However, they can normally replace each other. If you say: 他的男朋友只选重活干,把轻松的工作都留给了她. It's OK too.
When we have a list and let someone select one or some of them, we MUST use 选.
挑: select, pick
well... It means "select" too...
取: get
点: order (order some food in a restaurant)
It may be a little hard to distinguish them. If so, u can simply remember:
拣/捡/挑 = pick / choose
选 = select / choose
取 = 拿 = get
点 = order (in restaurant)
