malleable

1. Something that is malleable is easy to press or pull into a new shape (malleable steel)
2. Someone who is malleable can be easily influenced or changed by other people

In your own backyard, a much more malleable rule applies, which states that under some circumstances culturally manipulated landscapes are also worthy of protection, particularly when the original landscape has completely disappeared.

blow somebody away

to make someone feel very surprised, especially about something they like or admire

It just blows me away, the way everyone’s so friendly round here.

We were blown away by the United States.

be out of the question

if something is out of the question, it is definitely not possible or not allowed.

You can’t go in that old shirt – It’s out of the question.

Many people today have ancestors who lived in other countries, and this means that a gradual genetic separation of the people of the earth is no longer possible, and the development of different human species is out of the question – at least for now.

hold water

물이 새지 않다.

(이론, 설명 따위가) 이치에 맞다. 타당하다. (to be possible or believable)

If that argument held water, body builders would be packing on brain cells as well as muscle while they were at the gym.
