covet vs cosset

I somehow confuse the words covet and cosset. 

Covet means to desire possesion of something, particularly something someone else has: ‘I used to covet expensive cars but now they just give me the shits’. 

Cosset means to care for or protect something in an overindulgent way: ‘I tend to cosset passionfruit; they’ll often go rotten before I get to eat them and enjoy them’.
