Weiss is going to become a Ninja of hand-calling.

When two nouns are connected by “or”, the adjective that follows refers to the noun closest.

“Different than”, not “Different from”.

Exfoliate-  Pore cleansing
Defoliate- Leaf remova

Materiel- French term refering to war technology.

One and the same- idiomatic expression meaning two things that are equal.

Subjunctive- Also known as the counter-factual, the subjunctive is used if there is a doubt. 
e.g. If I were rich, I would have a lot of money.  However, I am not. 
If there once was doubt, but the doubt has been removed, it would revert to the past.
e.g. If I was broke before the promotion, I’m most certainly not now.
If there was a typo, it’s already been fixed.

Use whoever as a subject and whomever as the object.  However, if a sentence need both a subject and an object, the subject takes precedent.
