"However, if F is itself weak, then some or all of the key attributes of F supplied to E will be key attributes of one or more entity sets G to which F is connected by a supporting relationship"
This is from "Database Systems" by Garcia-Molina, Ullman & Widom which just happened to be lying at my left elbow on my desk. Weak entity sets are doubtless terribly interesting to people with a thing about relational data models, but as they bore the crap out of me I'm not going to even attempt either to understand or explain the above sentence.
