What is the exact difference between a latch & a flipflop?

Question Detail: 

From what I have understood :

1. A Flip Flop is a clocked latch i.e. flip flop = latch + clock
2. Latch continuously checks for inputs & changes the output whenever there is a change in input
3. Flip Flop also continuously checks input, but changes the output time determined by clock. [so, even though if inputs are changed, it may not change the output at the same time]
4. A latch with enable [i.e. gated latch], is different from that of clocked latch.

I am reading from Digital Logic by Morris Mano & Wikipedia.

As far as I understand, the difference is indeed the clock/enable.

A flip-flop samples the inputs only at a clock event (rising edge, etc.)

A Latch samples the inputs continuously whenever it is enabled, that is, only when the enable signal is on. (or otherwise, it would be a wire, not a latch).
