Spelling

ulterior	Other than or beyond what is stated or obvious	“alterior”	Heard, not read, in a region where “alt” and “ult” can sound similar; association with the word “alternate” with the “other/beyond” part of the definition	I still avoid this word.
shoo-in	A very likely winner	“shoe-in”, suggesting an image of golf wherein the player decides the ball is close enough to the hole to nudge in with his shoe.	We had Microsoft Golf around the time I learned the word and I unfortunately associated its animation for a “gimmie” with this.	I still avoid this.

obviate	To prevent or to preventatively make unnecessary	To make obvious	It seemed to make sense from the roots. It’s actually a false friend to “obvious”.	Since I found out what this word means I tend not to need it. A single word for “make obvious” would be far more useful.
