I am so delicious that I require a house to contain me.
I am a person who pretends to be someone else
In wealth I abound; in water I stand; as a fencer I'm valued all over the land; at Venice I'm famous; by farmers I'm prized; respected by law yet huntsmen despised; consternation and ruin ensue when I break; And the beasts of the forest advantage won't take.
I am commonly abbreviated to H

It flows out of the soil, It burns you if it boils, And holds us in its coils, More valuable than gold, As black as it is old.
