Match a leftmost prefix is quite not clear. Could you please explain it in a more clear way?

If we have a composite index like this idx(a,b,c). A leftmost prefix is a or ab or abc and so on. Any query pattern than can be covered by a leftmost prefix of the index can in fact utility this index. Is that more clear?
